The underlying system decomposes recordings of classical music performances into note events using score-informed source separation and represents the decomposed material using semantic web technologies. In a visual and interactive way, users can explore individual performances by highlighting specific musical aspects directly within the audio and by altering the temporal characteristics to obtain versions in which the micro-timing is exaggerated or suppressed. Multiple performances of the same work can be compared by juxtaposing and blending between the corresponding recordings. Finally, by adjusting the timing of events, users can generate intermediates of multiple performances to investigate their commonalities and di↵erences.

We examine the demands that such artists place upon their environments, the relationships between concepts and algorithms, and of cognition and computation. We begin by considering an artist's creative process, and situating it within the bricolage style of programming. An embodied view of bricolage programming is related, underpinned by theories of cognitive metaphor and computational creativity, and finally with consideration of the bricolage programmer's relation to time.

IDyOM offers a range of viewpoints which allow observation and prediction of various musical features. We used five viewpoints to measure the information content and entropy of musical events in songs. Analysis across the data shows absence of irregular musical structure in children's folk songs from Croatia, Serbia, Turkey, Portugal, Hungary, and Romania. Conversely, absence of regular structure in children's folk songs was found in Great Britain, Norway and Switzerland. Further analysis of (ir)regularity, by individual country, revealed the importance of patterns repeated at pitch in regular songs, and a higher occurrence of transposed repeated patterns in irregular songs. Principal component analysis (PCA) shows the salience of pitch and pitch intervals in the perception of (ir)regular structure. Neither rhythm nor contour affects the perception of regularity. Recurring pulse/meter and arch-like melodic structure were found in the majority of children's folk songs. The study shows that irregularity exists in children's folk songs, and that this genre can be complex.

The primary purpose of early music representation systems (that is, from ancient times until the beginning of musicology in the 18th century) was to record music for the purpose of reproduction by performers other than the composer and/or as aides memoire to the

Novelty search has been successfully applied to a wide range of domains and a number of variants have been proposed. Here we introduce Multiple Assessment Directed Novelty Search (MADNS), which exploits the notion that a diverse population optimised through phenotypic novelty may contain solutions to multiple conflicting objectives. We show that by utilising the MADNS algorithm, an evolutionary trajectory may be simultaneously directed towards conflicting objectives. We conclude that, through applying MADNS and MC-MADNS, a divergent evolutionary trajectory may be directed to provide simultaneous solutions to multiple conflicting problems in domains with large potential for exploration.

This includes natural language parsing techniques, using geometrical properties of space in language semantics, representation of execution flow in live coding environments, code as visual data and computer games as live coding environments. We will also touch on the unifying perceptual basis behind symbols, graphics, movement and sound.

By considering software construction as a creative writing task, we demonstrate how principles from story generation can be applied in software construction.
