QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. Music and shape: Exploring cross-modal representation Examples, a model and analyses QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. Professor Adam Ockelford University of Roehampton 11th March 2010 Music and shape How can the two relate? One set of dynamic relationships can be QuickTime™ and a TIFF (Uncompressed) decompressor created through movement: are needed to see this picture. • more or less freely associated with sound (eg, dance, gestures in performance) • creating, causing or controlling sound (eg, playing instruments, conducting) Music and shape Another set of relationships can arise through the visual representation of sound – the focus of this presentation QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. • Seven examples • Attempt to construct common theoretical framework • Indicative analyses • Discussion Children’s ‘picture scores’ 7 year old’s representation of a rhythm (after Bamberger, 1982) Children’s ‘picture scores’ 7 year old’s representation of a rhythm (after Bamberger, 1982) Blind children’s drawings on ‘German Film’ After Welch (1981) Blind children’s drawings on ‘German Film’ Conventional Western music notation Any features in common with children’s informal notations?

Excerpt from Stockhausen, Electronic Study No. 2 (1954) Score produced through synaesthetic response to music Jamie Roberts’s score of Jean Michel Jarre’s Oxygene (Track 4) How does it all work? A common underlying principle or principles? QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. Or fundamentally different processes at work? Perceptual domains • ‘Domains’ = way of modelling the fact that one sensation can have different ‘states’ • Touch: eg, temperature and pressure.

QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see thi s picture. Perceptual domains In music: - Pitch: (chroma, octave), harmony, tonality QuickTime™ and a - Perceived time: onset,decompressor duration TIFF (Uncompressed) are needed to see this picture. - Timbre - Loudness - Perceived location of sound source Different categories of domain Can be conceived as being QuickTime™ and a single dimensional, bidimensional or multidimensional TIFF (Uncompressed) decompressor are needed to see this picture. and as being linear or cyclical or both, or complex Examples … Duration Pitch QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. ‘Values’ • Each state in which a domain is perceived to exist can be conceived of as a ‘value’. • May be simple or complex (like the domains to which they pertain) • Example: Relationships within domains • Musical structure is not to do with individual values, but the relationships between them within each domain - particularly pitch and QuickTime™ and a perceived time TIFF (Uncompressed) decompressor are needed to see this picture. • We can assume that the relationships between values normally pass listeners by as series of qualitative experiences • However, they may be conceptualised (culture specifically?) as differences or ratios, or they may reflect the complexity of the values to which they pertain Examples of intra-domain relationships ‘Primary’ relationships Examples of intra-domain relationships ‘Secondary’ relationships Relationships between domains • Two main types QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. – ‘Regular’ (isomorphic in the domain of ‘shape’) – ‘Irregular’ (through association) Regular inter-domain relationships Guiding principle: to map values systematically QuickTime™ and a TIFF (Uncompressed) decompressor are needed to seedomains, this picture. between a relationship must involve a function that is not specific to the perceptual domains concerned. Regular inter-domain relationships For example, differences are domain-specific, so single values of difference cannot be mapped systematically between domains. Regular inter-domain relationships Whereas, ratios are abstract, are not bound by the context in which they occur. Hence they permit regular mapping between domains. Regular inter-domain relationships Ratios may occur between differences (as secondary relationships). Hence the regular inter-domain relationships would be tertiary. ‘Irregular’ inter-domain relationships Guiding principle: formed through association … either through repetition or indirect connection Irregular inter-domain relationships Different types: (a) arbitrary (repetition) (b) indirect (indirect connection) (c) synaesthetic (indirect connection) Arbitrary inter-domain relationships Any relationship between a sound and its visual representation (shape) is possible. For example: > accent • staccato QuickTi me™ and a TIFF ( Uncompressed) decompressor are needed to see thi s pi ctur e. fermata Arbitrary inter-domain relationships Example (‘staccato’) – relationship created through repetition (or verbal explanation = proxy repetition): Indirect inter-domain relationships Example (‘note cluster’) – relationship created through action / object as common visual and auditory source Can be reinforced through repetition Synaesthetic inter-domain relationships b Example – green corresponds to E major (and vice versa) Again, can be reinforced (for others) through repetition From theory to analysis Children’s ‘picture score’ Simplest interpretation: arbitrary relationships – given shape (circle) maps onto note Children’s ‘picture score’ More advanced interpretation: regular mapping of distance and duration; sequence and temporal order Score on German Film of pitch glide Coordinated regular mapping of vertical and horizontal distances with pitch and perceived time (implied tertiary relationships) Print score Arbitrary and semi-regular mappings combine (the latter reinforcing the former) Braille score Only arbitrary mappings survive transcription into Braille (which makes using this medium more challenging) Guitar tablature Combines both indirect and regular representations of pitch Stockhausen score: comprises regular representations of pitch, perceived time and loudness Jamie’s score: comprises regular and indirect representations of pitch, perceived time and timbre Conclusions • Evidence from children’s untutored representations of music suggests that sophisticated inter-domain mapping between sound and shape occurs early and intuitively • This view is reinforced by blind children’s representations of changing pitch – which are also sophisticated, and exist in the absence of any visual model to guide them Conclusions • The precise nature of inter-domain mapping may vary from individual to individual, and according to cultural convention. • However, it appears to be relatively easy to grasp regular mappings (consider, for example, widespread use of horizontal dimension for time and vertical dimension for pitch) or arbitrary symbols (as in standard notations) Conclusions • Some inter-domain mappings may be hard-wired through synaesthesia. • These seem to vary from individual to individual. • However, such representations can be learnt and appreciated by others Conclusions • What next? • More exhaustive search of different forms of symbolic visual representation of sound to check broad applicability of the model • Use the model to generate new forms of sound / shape installations • More research into how mappings aries and are learnt, and into sonic/visual synaesthesia Adam Ockelford [email protected] QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. 07818-456 472
