AUTOMATIC EXTRACTION OF TEMPO AND BEAT FROM
EXPRESSIVE MUSIC PERFORMANCES
Although variation in tempo is one of the main expressive parameters in
musical performance, most music still has an underlying tempo, that is,
a semi-regular sequence of times at which listeners might clap their
hands or tap their feet. In this talk, I will present a program that
automatically extracts these beat locations from musical performance
data in either audio or MIDI formats. A simple clustering algorithm
finds regularities in the times between the beginnings of notes, and
a multiple-hypothesis search is used to choose the sequence of beat
locations best fitting a model of musical accent and timing. The system
will be demonstrated in both its automatic and interactive modes,
performing tempo and beat extraction on music of various styles
(e.g. classical, pop, jazz).
