We are particularly interested in those emergent qualities of space that exist outside of\u2014but not without\u2014the performer, and seek to develop concepts and methods for mapping them. Based on the premise that we can never capture and notate these spatial qualities from one singular perspective, we produced descriptions from different disciplinary views. The six case studies \u201cfor a pianist and a self-playing piano\u201d conducted by Hanne Pilgrim, Adri\u00e1n Artacho, Leonhard Horstmeyer and Markus Kupferblum are seen as an intermediate step in the process of approaching our research goal of notating, creating, and communicating spatial phenomena.

We then introduce the self-playing piano CEUS by B\u00f6sendorfer as a research tool. Subsequently we outline six case studies\u2014each investigating different spatial qualities\u2014with frequent excursions into the different disciplinary perspectives to convey a more sophisticated description of said spatial phenomena. We conclude the article by presenting the output of the case studies.<\/p>\n<h4 id=\"2\">Investigating Spatial Qualities\u2014a Cartographic Methodology from Six Perspectives<\/h4>\n<p>In this section we discuss the methodological approach used in our investigations. What do we mean by spatial qualities? What do they pertain to? When do they arise and how may one explore them? Spatiality has long been elevated from a purely physical quantity to a more relational\u2014and partly abstract\u2014concept. The work of Descartes in particular has paved the way for embedding relational phenomena into a spatial context via the so-called Cartesian coordinate system. But also the notation of music has profited from the projection of qualities such as pitch or duration onto some spatial representation of musical phenomena. Here we refer to spatiality as encompassing relational aspects, textural and structural spatial aspects, directional and intentional aspects, as well as experiential aspects. The relational aspects include such concepts as constraining, containment, adjacency, segmentation, marginalization, and voidness. The textural aspects include smoothness, friction, stickiness, and striation. The directional aspects include rising and sinking on scales or ladders, the changing chromaticity, but also attack and rebound of bodies. Intentional and experiential aspects both pertain to a subject, with the distinction that the former are directional in nature, while the latter are not. Experiential aspects include the sensations of floating, of being dragged, or of resting. Each of these examples have spatiality pertaining to them, not exclusively but significantly and sometimes vastly.<\/p>\n<p>In order to explore these respective spatial qualities we have developed six case studies that cover relational, textural, structural, directional, intentional, and experiential spatial aspects. Each case study focuses on a subset of these aspects. The subject of study is a performer, in our case a pianist, and a programmable grand piano. Additionally we also have a physical space in which they are situated, and one or two observers. One of the observers is a capturer, namely a videographer.<\/p>\n<p>The exploration of a plentitude of spatial qualities through a set of case studies forms the core of our cartographic approach. Each case study is like a little chart of an atlas of spatial qualities. This is the overarching guiding methodological theme of this research. Since some studies share a spatial aspect, there is an overlap that allows one to go from any chart to an overlapping adjacent chart. This process of passing from one chart to another can be thought of as a transition map between two charts. When turning the page of an atlas one will find that certain geographic landmarks are present on both charts. This is the overlap that allows for a transition between charts.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.mdw.ac.at\/mdwpress\/wordpress\/wp-content\/uploads\/Pilgrim_Fig1.jpg\" alt=\"Three men in a studio setting, one adjusts a light, another operates a camera, and two others discuss notes by a green screen, appearing focused and collaborative.\" width=\"2500\" height=\"788\" class=\"alignnone size-full wp-image-6653\" srcset=\"https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1.jpg 2500w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-300x95.jpg 300w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-1024x323.jpg 1024w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-150x47.jpg 150w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-768x242.jpg 768w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-1536x484.jpg 1536w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-2048x646.jpg 2048w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-104x33.jpg 104w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-850x268.jpg 850w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-1240x391.jpg 1240w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-320x101.jpg 320w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-309x97.jpg 309w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-742x234.jpg 742w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-496x156.jpg 496w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-618x195.jpg 618w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig1-413x130.jpg 413w\" sizes=\"auto, (max-width: 2500px) 100vw, 2500px\" \/><br \/>\n<span class=\"caption-text\"><strong>Figure 1:<\/strong> Sequence of stills from the 5<sup>th<\/sup> case study, <em>Molteplicit\u00e0<\/em> for a pianist and a self-playing piano. \u00a9\u00a0Markus Kupferblum<\/p>\n<p>How can one pursue the charting of spatiality through case studies? Our approach in this regard focuses on a particular artistic practice and a particular setting, namely the relation between a pianist, a programmable self-playing piano, and the ambient space. Both the pianist as well as the composer iterate for each study on a theme that facilitates and illuminates a certain spatiality. For each case study we proceed as follows: First we raise the artistic research questions that this study is concerned with.

We found it useful to use the structure of Italo Calvino\u2019s <em>Lezioni americane<\/em> (published in English as <em>Six Memos for the New Millenium<\/em> in 1988) as a prompt to re-imagine the qualities of the space inhabited by the pianist in our investigations. Calvino devotes each of his lectures to one of the literary qualities he values most: lightness, quickness, exactitude, visibility, multiplicity, and consistency. These concepts\u2014loosely appropriated and reinterpreted in the context of the audio-corporeal arts\u2014helped articulate our shared thinking about space, crystallizing in a series of six case studies \u201cfor a pianist and a self-playing piano\u201d that each bear the name of one of Calvino\u2019s lectures. Note that Calvino died before being able to finish his <em>Lezioni americane<\/em>, leaving everyone to speculate about the content of his last lecture. We nonetheless produced a last case study that explores the concept of consistency from different perspectives.<\/p>\n<h6>1.

Carefully, the pianist approaches it until she is close enough to hit a specific chord, which stops the keys momentarily. The performer is engaging with the piano in a playful manner and explores the acoustic and responsive range of the CEUS. By exploring the range of dynamics and pitch she opens up the space of possibilities and at the same time constrains them by delimiting the extremes. During one of her movements she probes the highest and the lowest keys of the piano or she probes the simultaneous attack of as many keys as possible, respectively to test the response of the piano. She applies attacks with varying levels of pressure and assertiveness to probe the rebound and the general response of the piano. Here she uses a playing technique in which certain tones are filtered out of a sounding cluster with the effect of creating a harmonic echo. In the end of this first movement, the pianist leaves the piano which is still busy replaying the chords she had played before like a reverberation of the common interaction. The pedal does a long shaky shadow of her foot movements. The pianist*performer writes:<\/p>\n<blockquote>\n<p class=\"tsquotation\">As I approach CEUS I try to unburden myself of any expectation and turn to listening and observing the whimsical and at the same time tender own movements of its keys. I take a seat. I stay until I can no longer restrain myself from testing and interacting with it. I have never interacted with a piano like this before. Now the challenge is to elicit a dramaturgy from the play that unfolds from our interactions and to integrate all unplannable events en passant in the process. As the arc of the piece clearly draws to a close for me, I let CEUS play the coda for us alone.<\/p>\n<\/blockquote>\n<p>The video concept for <em>Leggerezza<\/em>, in its documentary format, directs all the attention to the interaction between the piano and the pianist. In favor of the presence of the two bodies, the director\u2019s presence and the shooting process remain in the background.<\/p>\n<p>The pianist\u2019s handling of the piano is akin to the act of searching for an escaped pet in a space where the doors and all conceivable escape routes are closed. The search may be carried out in this constrained space, which nevertheless still leaves a lot of room. In the practice of mathematical research it is also common to delimit a question in this way. One often tests whether a statement holds at the extreme scenarios in order to get a first feeling for it. In testing for the range, the performer makes use of the Newtonian principle of action and reaction, presenting us with a twisted sense of causality as a result; to all accounts, the piano seems to sometimes initiate actions of its own accord. In stark contrast to the experience of a life-long piano practice, here the performer ought to negotiate every action with the instrument, to the extent that we may consider agency to be distributed across the system.<\/p>\n<p>Another spatial aspect that appears\u2014or rather disappears\u2014in this piece is that of the void. On one hand, the interaction between the performer and the piano takes place through subsequent \u201ccontact events,\u201d where the pianist\u2019s body encounters the surface of the keys, portraying manifold variations of pressure, length, velocity\u00a0\u2026 On the other hand, though, the piano keeps sometimes responding in her absence, as though she were present. The concept of a void has inspired generations of physicists and lies at the very core of our metaphysical idea of the world: Is there anything without anything? This question asks about the existence of space without matter. For a long time people have believed that a sort of substance called ether permeates space. Even though this concept has become unfavorable in the light of the Michelson-Morely light-interference experiment, the question remains: What is there where nothing is? This piece poses a similar question by presenting the bodiless gap between the piano and the performer\u2014the void\u2014as a territory in dispute that shrinks and expands with the advances of each contender. Moreover, the use of the \u201cfiltering\u201d<a href=\"#fn24\" class=\"footnote-ref\" id=\"fnref24\" role=\"doc-noteref\"><sup>24<\/sup><\/a> technique towards the end of the piece resonates with the notion of negative space, a literal subtraction of the weight that nudges the piece towards its final resting point.<\/p>\n<h6>2. Rapidit\u00e0 (quickness)<\/h6>\n<blockquote>\n<p class=\"tsquotation\">\u201cAgility, mobility, and ease, all qualities that go with writing where it is natural to digress, to jump from one subject to another, to lose the thread a hundred times and find it again after a hundred more twists and turns.\u201d<br \/> Italo Calvino, <em>Six Memos for the New Millenium<\/em><a href=\"#fn25\" class=\"footnote-ref\" id=\"fnref25\" role=\"doc-noteref\"><sup>25<\/sup><\/a><\/p>\n<\/blockquote>\n<p>How many jumps, twists and turns do pianist\u2019s hands make when following a musical flow of thoughts in an instant composition? How does she digress while surrendering to a certain movement, texture, harmony, or rhythm? How does she find her thread again? What does quickness even mean for a piano\u2019s body?<\/p>\n<p><em>Rapidit\u00e0<\/em> is, perhaps as a result of the high density of action, a brief piece. The principle of tone repetition with consistent hand changes is maintained for the entire course, whereby the pitches change and the movement also alternates between unisono playing and clusters. The pianist*performer writes:<\/p>\n<blockquote>\n<p class=\"tsquotation\">The first question I ask myself is what quickness is meant to be from a pianistic point of view. Obviously there are so many facets to being quick (mentally, musically, bodily) depending on where you look. Quick reaction and quick release as central aspects of piano playing can be transferred to various activities of the body and mind: movements of the fingers, wrists, arms, feet, gaze, thinking movements in processing and planning, breathing movements. How do I face the discrepancy between what feels fast from my perspective of acting and what feels fast from an outside reception. I assume that sound production and sound effects are often not congruent. Focussing on the conditions of the piano: how can I challenge the piano\u2019s body in terms of quickness? The expectation of a good key action is among other things linked to how cleanly and quickly the key returns after being mobilized by the pianist. Tone repetitions are a tool to check and evaluate this. So I throw myself into the competition with gusto and repeat a key. The resulting principle of exertion and recuperation forms the basis for the emerging music.<\/p>\n<\/blockquote>\n<p>We discuss two spatial concepts that are present in this piece from a mathematical point of view: Accumulation and Resolution. Accumulation is a core concept in the mathematical field of analysis. It is possible and indeed common for a succession or a series of points to inch towards a point that may or may not be reached, as suggested by the quick succession of notes that propel the piece towards some uncertain resolution ahead in time. This is akin to the idea of throwing darts at a target without ever hitting its center. The failed attempts will however accumulate around the center. Resolution of space and time, on the other hand, figures most prominently in the concept of a Fourier transform.<a href=\"#fn26\" class=\"footnote-ref\" id=\"fnref26\" role=\"doc-noteref\"><sup>26<\/sup><\/a> Translating a signal from one medium to another, for instance from the fingers to the piano keys and then to the hammer, may result in a lag or a smoothening that effectively alters or crops the high frequency modulations. A repeated attack on a piano key can at some critical attack velocity not be resolved any further due to mechanical constraints of the hammer. The ear for instance cannot resolve very high pitches, because of the ear physiology.<a href=\"#fn27\" class=\"footnote-ref\" id=\"fnref27\" role=\"doc-noteref\"><sup>27<\/sup><\/a><\/p>\n<p>The long chain of repeated notes is not\u2014at least initially\u2014perceived as motivic material, but as belonging to a narrow space conformed by the accumulation of intensities in the Deleuzian sense.<a href=\"#fn28\" class=\"footnote-ref\" id=\"fnref28\" role=\"doc-noteref\"><sup>28<\/sup><\/a> The properties of said space seem to emerge from this simple accumulation, rendering the speed at which the performer is able to actuate the keys its most expressive parameter.<\/p>\n<h6>3. Esattezza <em>(exactitude)<\/em><\/h6>\n<blockquote>\n<p class=\"tsquotation\">\u201cTo my mind, exactitude means three things above all: (1) a well-defined and well-calculated plan for the work in question; (2) an evocation of clear, incisive, memorable visual images; (3) a language as precise as possible both in choice of words and in expression of the subtleties of thought and imagination.\u201d<br \/> Italo Calvino, <em>Six Memos for the New Millenium<\/em><a href=\"#fn29\" class=\"footnote-ref\" id=\"fnref29\" role=\"doc-noteref\"><sup>29<\/sup><\/a><\/p>\n<\/blockquote>\n<p>In his own literary work, Calvino cultivates this quality of exactitude through the use of structural patterns and numerical systems. But which affordances does the self-playing piano\u2014as opposed to a regular piano\u2014offer a pianist in terms of exactitude? What is a well-defined and well-calculated musical expression? Can we shift the idea of clear, incisive and memorable images from visual to audio-corporeal?<\/p>\n<p>This piece begins with the pianist placing a 13\/8 ostinato pattern, which is rhythmically full-beat but has an upbeat effect in the repetition due to the division 222223. Harmonically, the three-part pattern plays with friction and resolution. CEUS takes over the pattern immediately after a run, so that the pianist can add further voices to the looped pattern. At that point, the piece becomes a duo of sorts,<a href=\"#fn30\" class=\"footnote-ref\" id=\"fnref30\" role=\"doc-noteref\"><sup>30<\/sup><\/a> the looped pattern dutifully accompanying the successive layers added by the pianist as the piece unfolds. The way these layers fall into place against the backdrop of the looped pattern holds a palpable structural tension until it ultimately diffuses in a fadeout with a ritardando, the voices quietly rippling out of the rhythmical harness that appears to have held the piece together all along. The pianist*performer writes:<\/p>\n<blockquote>\n<p class=\"tsquotation\">What makes working with CEUS so special is the feedback the piano gives me\u2014not only in the usual form of haptics and acoustics, but in very concrete pianistic (interlocking) events and musical textures. What is transient and fleeting in other repertoire playing can be recycled here and kept moving. In the case of the 13\/8 reference pattern CEUS\u2019 repetitions of my initial input are precise and inescapable in timing. This circumstance forces my attention to rhythmic accuracy. At the same time I am challenged to be at ease with the asymmetry of the pattern, to place it in a mindful and easy way. After Guilherme Schmidt and Danielsen when being in a groove, the relation of subject and object is almost suspended within a continuous field where the limit between music and musician\/listener\/dancer has vanished.<a href=\"#fn31\" class=\"footnote-ref\" id=\"fnref31\" role=\"doc-noteref\"><sup>31<\/sup><\/a> This describes quite well my experience of interacting with CEUS. The more motives we exchange and loop, the more blurred it becomes as to who is playing what. My impression of the spatial quality can be described as a balancing of weights, fragile and stable at the same time. My kinesthetic gestures unfold between control and devotion.<\/p>\n<\/blockquote>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.mdw.ac.at\/mdwpress\/wordpress\/wp-content\/uploads\/Pilgrim_Fig3.jpg\" alt=\"A person plays the piano in side profile, seated at a grand piano.

In the control-theoretic formulation the sensorimotor loop can be seen as a problem of proportional, integral, and derivative control. Each control tries to place the motoric response in an optimal way, but the proportional one achieves this through correcting possible mistakes in the magnitude of their appearance, whereas the integral and derivative controls try to steer the motorics in relation to the cumulative deviation or the relative change of the deviation respectively. Also from a communication-theoretic standpoint the sensorimotor loop presents us with an interesting problem. How can sensorimotor systems optimally respond to their environment? How does the rebound of the pedal and the general mechanical feedback on the tactile senses inform an optimal motorical response?<\/p>\n<p>The space surrounding the performer\u2014the keys, the pedaling, etc.\u2014is therefore shaped by the looped ostinato which, akin to a stubborn memory, keeps arising again and again in the same precise pattern. As listeners, we anticipate the repetition and hence become hyper-aware of the slightest rhythmic imprecision. This heightened rhythmic sensitivity informs the performance (must adhere to the rhythmic grid) and allows it to only evolve over time \u201cvertically\u201d by introducing additional layers on top of the ostinato. The \u201cotherness\u201d of the looped accompaniment is expressed visually through the mirror set opposite the performer, giving the impression of an actual piano duo.<\/p>\n<h6>4.

The narration unfolds in the theater of the observer\u2019s imagination.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.mdw.ac.at\/mdwpress\/wordpress\/wp-content\/uploads\/Pilgrim_Fig4.jpg\" alt=\"Collage of intense piano playing moments; hands striking keys and inside strings, a woman leaning and focused, capturing passion and musical precision.\" width=\"2500\" height=\"1014\" class=\"alignnone size-full wp-image-6656\" srcset=\"https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4.jpg 2500w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-300x122.jpg 300w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-1024x415.jpg 1024w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-150x61.jpg 150w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-768x312.jpg 768w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-1536x623.jpg 1536w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-2048x831.jpg 2048w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-104x42.jpg 104w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-850x345.jpg 850w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-1240x503.jpg 1240w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-320x130.jpg 320w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-309x125.jpg 309w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-742x301.jpg 742w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-496x201.jpg 496w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-618x251.jpg 618w, https:\/\/www.mdw.ac.at\/mdwpress\/wp-content\/uploads\/Pilgrim_Fig4-413x168.jpg 413w\" sizes=\"auto, (max-width: 2500px) 100vw, 2500px\" \/><br \/>\n<span class=\"caption-text\"><strong>Figure 4:<\/strong> Stills from the video piece for <em>Visibilit\u00e0<\/em>, further exploring the space around the performer by means of overlaying multiple perspectives in different ways. The visual concepts for the pieces were largely contributed by theater director and video artist Markus Kupferblum. \u00a9\u00a0Markus Kupferblum<\/p>\n<p>The pianist*performer writes:<\/p>\n<blockquote>\n<p class=\"tsquotation\">The piano expresses itself in such a peculiar way with rhythmic keyboard group actions that it takes me a moment to interpret that these strange keyboard gestures are movements similar to language. Different, however, from musical gestures that simply resemble speech, but almost imitating a person with a certain speech habitus. After making my presence felt through some brief pianistic interjections, I find that this kind of dialogue with the talking piano does not lead to the development of a common musical texture and I retreat to interactions through touching and not triggering sounds from various body parts beyond my hands. In the process, of course, I listen very attentively to the piano\u2019s speech, commenting, interrupting, supporting it with my movements. I approach the piano\u2019s body with my own body; I dance with it, I move through its acoustic and physical, corporeal spaces.<\/p>\n<\/blockquote>\n<p>The video to this piece is elaborate and playful. The filming process is consciously present; one sees props and utensils belonging to the filming in the picture again and again. The visual language of the video is intimate. The camera focuses on sections of the two bodies. It then gives rise to forms that are not always clearly assignable. The play with sharpening and blurring reinforces the formation of interwoven image structures, contributing to a polyhedral representation of the space inhabited by the performer. Rather than following a conventional musical development, the piece can be better described as an accumulation of evocative images conjured by the piano speech,<a href=\"#fn35\" class=\"footnote-ref\" id=\"fnref35\" role=\"doc-noteref\"><sup>35<\/sup><\/a> the performer\u2019s body movements, and a unique visual language holding it all together. There is a particular spatial quality in the bodies\u2014their forms, colors, skin, landscapes\u2014and in the surreal imagery that results from their fusion, the intimacy afforded by the close-ups, and the relationship of alterity suggested between body actions and piano utterings, insofar as their respective spaces are superimposed, yet not necessarily connected.<\/p>\n<h6>5.

How are the musical actions of the pianist influenced by the observer close-up\u2014even reaching into her kinesphere\u2014while a composer interacts with the piano through multiple interfaces whose actions are being captured by the camera?<\/p>\n<p>What begins as a mystery in <em>Leggerezza<\/em> and remains a mystery in the other memos is deliberately woven into the composition in <em>Molteplicit\u00e0<\/em>: the beforehand invisible but actively composing parties are now shown. It is a piece which unfolds itself through the focus of the camera. At first, the camera\u2019s gaze only accompanies the composer, who controls the piano via MIDI, and only later turns to the pianist, the observer creating attention spaces, and then to himself in the mirror. The pianist*performer writes:<\/p>\n<blockquote>\n<p class=\"tsquotation\">In this piece, my attention travels back and forth between the physical space and the virtual space created by the camera. In the first, I observe how the pleasantly concentrated focus of the observer looking at the piano and me at close range affects my musical sending. In the second, I look at myself as if from a distance from the perspective of the person accompanied by the camera. My attention thus rotates, expanded by three new perspectives that I seek to integrate into the flow of the music.<\/p>\n<\/blockquote>\n<p>The repeated composition of basic transformations, such as reflection, scaling and transposition in pitch and temporal dimensions creates ever more complex patterns, both in the temporal and the tonal dimension. How can one understand this complexity and its degree? The more often the transformations are carried out, the more intricate, the more fine-grained and the more complex the resulting output appears to become. In the theory of fractals, one frequently encounters and invokes the concept of a Hausdorff-dimension to capture this degree of complexity. The idea is that a one-dimensional thread that is folded again and again and so forth eventually will behave a little bit like a two-dimensional quantity, but not quite. Repeated transformations of two-dimensional qualities behave more three-dimensionally and so on for ever higher dimensions. The extent to which it behaves higher-dimensionally is captured by the Hausdorff-dimension. In some sense, it measures how much new space is created. The space created around the performer is also subject to these fractal multiplications, the whole of it virtually contained in the very reduced contact point between performer and instrument, analogous to how musical textures appear to sprout from relatively simple performer\u2019s actions. The abrupt closing of the fallboard at the end seems to make the fragile architecture of the piece collapse in one brutal blow, the resonance of which gives place to an almost oppressive silence\u00a0\u2026<\/p>\n<h6>6. Coerenza <em>(consistency)<\/em><\/h6>\n<p>The last of Italo Calvino\u2019s lectures was never written due to the untimely death of the writer. We are left with the title this lecture would have had: <em>Coerenza<\/em> (consistency). We can only speculate what Calvino might have had to say about consistency in literature but what does consistency mean with reference to an audio-corporeal expression?<\/p>\n<p>For this last piece we decided to integrate the algorithmic output generated by the computer with the performer\u2019s actions in a way that would behave almost like an extension of her body. One motivation was to push back the feeling of otherness we had sometimes identified in the previous case studies. The musical concept underlying the piece addresses the principle of repetition and variation as the piece progresses. While a simple motive is repeated and shaped, its surroundings are changing in terms of harmonic accumulation, dynamics, and additional feedback layers like changing aggregate states. While the pianist sits at the instrument almost motionless, her kinesthetic gestures are changing in attack and muscle tone. Her gaze oscillates between a focused \u201cspotting\u201d and a softer peripheral view. The pianist*performer writes:<\/p>\n<blockquote>\n<p class=\"tsquotation\">With the idea of changing consistencies in my mind, I try to look for them in the music, to grasp and move them. This focus triggers changing levels of tension in my playing movements and in my listening. My gaze also changes its spatial reference in a constant change of its quality. Here I perceive the camera as a co-player. It mirrors my constant mental transformation through its constancy and direction.<\/p>\n<\/blockquote>\n<p>Coherence is also an important aspect of wave dynamics: two waves are coherent if their phase difference stays constant. More generally the coherence of two waves is a measure of their correlation. If two signals have deviating amplitude or frequency, then the two signals are said to be incoherent. Loosely speaking coherence measures the alignment of two signals. Consistency on the other hand is a property of mathematical theories, namely the lack of logical contradictions. If one argument or theorem stands in contradiction with another theorem, then these two statements are inconsistent. One could also describe <em>Coerenza<\/em> in those terms, stating the (dis)alignment of the computer generated motives with respect to the performer\u2019s actions as the main principle structuring the piece, from a highly coherent initial state to a sequence of perturbations, progressively reabsorbed as the system finds its way again to the initial balance.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.mdw.ac.at\/mdwpress\/wordpress\/wp-content\/uploads\/Pilgrim_Fig5.jpg\" alt=\"Three images show a woman in red against changing backgrounds: a green cloth, white, and an underwater scene.

We find that our approach, albeit not necessarily systematic, did help us think anew about space in original ways. This is not to say that the work was without its challenges. Since the different steps in the research process took place in different constellations and settings, we had to constantly realign ourselves and let go of expectations in order to make productive decisions and come to an output which represented the respective spatial topic we were investigating. For instance each of the involved researchers was working partly in peer-to-peer, and partly alone. We had restricted time slots with the CEUS piano. The compositions as musical pieces had different requirements than the audio-visual compositions with video etc. We found that we could face these challenges by working on iterations as different versions of each piece. These we consider to be \u201csnapshots\u201d of a moment in time of the artistic research process. In terms of the musical structure, we found it productive to let go of the pianistic repertoire or through-composed music in favor of loose sketches that allowed the performer to explore the material in-the-moment. We shaped our workflow in order to maximize flexibility at the moment of the performance, which was fundamental in confidently addressing the desired spatial qualities we wanted to map. We therefore focused on the stage where the performer IS in the space, and did not preempt the output by fixing the notation or compositional system too much. We also hope that the output of the project, including the artistic research methods developed for these case studies will provide valuable insights into the artistic research community.<\/p>\n<p>The audio-visual output of the project, the cycle <em>Six Memos for a Pianist and a Self-Playing Piano<\/em> consists of six video pieces presenting each of the case studies. The video playlist can be accessed using the QR code at the end of this paragraph. We recommend that it be viewed together with the sketches that make up this article for clarity.<\/p>\n<p>In order to pursue this artistic investigation, we also developed a library of MaxForLive devices (TesserAkt) that perform all sorts of operations in the MIDI realm. These modules can be stuck in any configuration and connect to one another using MIDI CC messages.
