Hello Everyone,

Apologies for Cross Postings

This is an invitation from the University of Edinburgh MusIC group to
please join us for a talk by Professor Petri Toiviainen from The 
University of Jyväskylä.

Petri Toiviainen: "Measuring, Modelling, and Visualizing the Dynamics 
of Tonality"

Tuesday 6 February 2007 at 1715, Student Common Room, Alison House, 
School of Music

Abstract
Perception of music is an active dynamic process: while music unfolds 
in time, we constantly form expectations about its possible 
continuations. These expectations operate on several levels of music, 
such as melodic, harmonic, rhythmic, and tonal. The fulfilment or 
violation of these expectations gives rise to patterns of tension and 
relaxation, which, it has been suggested, is one source of emotions 
evoked by music. Therefore, understanding dynamical aspects of music 
perception is crucial for obtaining a more comprehensive picture of the 
musical mind. The dynamics of music perception can be studied with 
various methods, including listening experiments and computational 
modelling.

Music in many styles is organized around one or more stable reference 
tones. In Western music, this phenomenon is referred to as tonality. As 
music unfolds in time, the tonality percept often changes. For 
instance, the clarity of tonality can change over time. Furthermore, 
the particular piece of music may contain modulations from one key to 
another. These changes in perceived tonality may be important in the 
creation of expectancies, tension, and emotions.

I will discuss methods for measuring the dynamics of music perception, 
in particular the perception of tonality, by means of listening 
experiments. Furthermore, I will talk about approaches to simulate this 
process with models of pitch perception, short-term memory, and the 
self-organizing map (SOM). The SOM allows for dynamic visualization of 
perceived tonal context, making it possible to examine the clarity and 
locus of tonality at any given point of time. Finally, I will discuss 
computational methods for the analysis of tonal structure of musical 
works.


This is the first talk of the semester so we hope you can come.  It 
should be quite enjoyable, with plenty of opportunity for questions and 
lively discussion afterwards.

Please feel free to forward this invitation as appropriate.
