Workshop 10-11 March 2010
Shaping music in performance: Structure, memory and shape
Dr Jane GinsborgCentre for Music Performance Research, RNCM
Outline of talk
• Shape: some definitions
• Memory expertise and structure
• Effective memorising of music – advice and experiments
• Shared performance cues: understanding of compositional structure; effects on recall
• Beating time
• Shaping contour: bodily movement
• Summary and conclusion: mental representations revisited
Shape: some definitions
• A particular kind of mental representation
• Questionnaire survey on Music and Shape seeks expert musicians’ reports on representations evoked by the word “shape”
• For me as a performer = “structure”
• Also “contour” (of pitch and dynamic – NB often associated cf Schumann’s Mondnacht)
pp
Memory expertise and structure
• Method of loci: Cicero De Oratore (55 BC)
• Simonides (556-468 BC)
• Theatre of memory – birth of mnemonics
1. Relies on representation of table, theatre, house etc., and ability to “walk” round it
Memory expertise
• Ericsson, Chase & Faloon (1980)
• Extended normal digit-span by utilising knowledge of running times to make associations e.g.
• 3492 = “3 minutes and 49.2 seconds, near world-record mile time
Effective memorising of music
• Cognitive analysis - identifying key changes, harmonic structure, length of rests, difficult exit points (Hallam, 1997 – interviews)
• Use of compositional structure– To guide practice (Chaffin & Imreh, 1997) – As retrieval scheme to perform from memory
(Taylor et al., 1999) – Longitudinal case study method (Chaffin et
al., 2002)• Impossible without information in LTM re
sections, phrases, sub-phrases etc.
Advice: analyse before learningEdwin Hughes (1915). Musical memory in piano playing and piano study. The Musical Quarterly, 1, 592-603
Tobias Matthay (1926). On Memorizing and Playing from Memory. Oxford University Press
Experiments
• Benefits of analysis (Rubin-Rabson, 1937; Ross, 1964)
• Use of structural boundaries to guide practice:
– more so in skilled pianists; developed over course of practice sessions (Williamon & Valentine, 2002)
– singers (Ginsborg, 2002)
Development of shared performance cues
• Ginsborg, Chaffin & Nicholson (2006a)
• Singer’s and conductor’s understanding of compositional structure
• Ricercar 1 from Stravinsky’s Cantata
Longitudinal case study method • Chaffin, Imreh & Crawford (2002)
(and many other papers since 1994)
• One pianist – 33 hours’ practice /
memorisation of Bach’s Italian Concerto
– one performance (a commercial CD)
– Written-out free recall of first page two years later
More recent case studies
• Jazz pianist (Noice, Jeffrey, Noice & Chaffin, 2008) – 45 minutes preparation and one performance
• Cellist (Chaffin, Lisboa, Logan & Begosh, 2009) – also Bach – 33 hours preparation, multiple performances, free and cued recall
• Students – http://www.htfdcc.uconn.edu/psyclabs/musiclab.html– http://www.htfdcc.uconn.edu/psyclabs/SYMP.html
The opportunity
• Projected performance of Stravinsky’s Cantata for soprano and tenor soloists, small instrumental ensemble and women’s choir in December 2003 at Firth Hall, Sheffield
• Ricercar 1 for solo soprano and instrumental ensemble
• Conductor / rehearsal pianist: George Nicholson• Soprano soloist: me
Theoretical framework• Performer attends to important features of the music
while practising / rehearsing (basic, structural, interpretive, expressive)
• Some of these stop being perceived as important• Others are attended to automatically• The remainder are retained as retrieval or
performance cues – landmarks in the performer’s mental representation of the piece – when performing from memory
• Converging evidence that attention to features that become performance cues determines what is practised… and subsequently, what is forgotten
Shared performance cuesProcedure (1)
• Video-record all individual practice sessions, joint rehearsals (ten in all lasting 8 ½ hours) and performance
• THEN determine transcription and analysis methods (to avoid “demand characteristics”)
• Give performance
• Post-performance reports: indicate musical features and PCs on multiple copies of score
• Calculate start-and-stop beats for every practice segment

Beating time
• Aim: to investigate associations between singer’s practice and rehearsal behaviour (start-beats, stop-beats and repetitions)…
• …with different kinds of movement – pulsing, conducting and gesturing, and no movement (NB independent judge) –
• …and musical features/performance cues
• Method: as before but with multiple rather than mixed hierarchical regression analysis
Sessions 1 and 2 (individual: learning): pulse beating, conducting
Session 3 (individual, memorising): conducting
Sessions 5 (individual, memorising) and 6 (joint): pulse beating, conducting, no movement
Session 8 (individual): conducting, gesture
Sessions 9, 12 and 15 (joint): gesture, no movement
Outline of findings
• Different kinds of body movement are associated with kinaesthetic learning at different stages of the process of preparing to perform from memory
• Beating a pulse provides framework for ensuring rhythmic accuracy
• Conducting during memorizing phase helps form metrical representation – SHAPE
• Gesture – once piece is learned and memorized – underpins communication of semantic meaning (musical or verbal)
• Need for singer also to practise not moving in preparation for performance
Beating time
Ginsborg, J. (2009). Beating time: the role of kinaesthetic learning in the development of mental representations for music. In A. Mornell (ed.) Art in Motion. Vienna: Peter Lang.
The story so far
• Shared performance cues
1. Verbal commentaries and discussions: content analysis of four sample practice sessions / rehearsals
• Cognitive, metacognitive and hints at social processes
2. Annotations (representing features and PCs) as predictors of very long term recall via practice behaviour (stops, starts, repetitions)…
3. …with and without bodily movement (singer only)
Shaping contour: Bodily movements
• Study of “gestures and glances” (Ginsborg & King, 2009; King & Ginsborg, forthcoming [2010])
• Research questions: How do performers’
1. bodily movements (“gestures”) and
2. use of eye contact (“glances”) compare
• when they collaborate in ensemble rehearsal with performers of different levels of
A.Expertise (student vs professional)
B.Familiarity (regular vs new duo partners)

Metaphoric gestures
Convey musical information
Discussion: gestures in relation to music
• Contribute to the development of mental representations for formal structure (cf Williamon & Davidson, 2002)
• Pianists’ gestures primarily expressive and communicative; singers’ gestures support technical production of sound and convey information
• “Movement-related information may be limited to relatively general, instrument-independent forms of body motion, e.g. swaying, rocking and expressive gesturing” (Keller, 2008, p. 209)
Discussion: effects of familiarity and expertise
• Closer harmonisation of gestures in established duo: “combined rhetoric” of movements
• Ensemble performers anticipate, attend and adapt to their own and each others’ playing (Keller, 2008)…
• …so as to develop joint mental representations and implement shared decisions; auditory and motor information
• Complemented by verbal information (Ginsborg & King, 2007ab, 2008)
Summary and conclusions: mental representations revisited
• Understanding of structure (and structural boundaries) crucial to memory
• Shared performance cues research – serial chaining (block signalling) vs content addressability (centralized traffic control)
• Beating time – role of kinaesthetic memory in forming mental representation of metrical structure
• Shaping contour – role of bodily movement (also kinaesthetic memory?) in creating mental representation of meaning
