"Acquisition et Representation de Connaissances en Musique"

Ph.D. thesis in Theoretical Computer Science, by Bernard Bel.
Defended at Aix-Marseille III University on 28 November 1990

Text in French (208 pages)

English Abstract:

This study deals with computer representations of musical knowledge
based on two real-scale experiments. The first experiment focusses on
knowledge acquisition in ethnography (Kippen-Bel's project on North
Indian drumming): an expert (the musician), an analyst (the
musicologist), and a machine interact in a learning situation.
Improvisation schemata through which musicians express their musical
ideas are identified and formalized with production rules in a formalism
derived from generative grammars and pattern languages. A deterministic
algorithm is introduced for assessing the membership of arbitrary
strings to the langage defined by a given (context- sensitive) grammar.
A technique for the inductive inference of regular languages is
presented, enabling automatic knowledge acquisition of syntactic and
lexical knowledge.

The second experiment is part of the design of a computer environment
for musical composition ("Bol Processor BP2"). Here the specific
problem centres on time representation in a discrete structure of "time
objects", and the more general problem on the synchronization of
parallel processes. A method is outlined for determining a structure
without complete data on the synchronization of its objects. The
concept of "sound object" is then formally introduced. An efficient
algorithm is proposed for the time-setting of objects in a structure,
given the constraints arising from their metric and topological

Keywords: formal languages, membership test, grammatical inference,
synchronization, time representation.

I just received the following note:

Dear Subscriber,
Thank you for your subscription to Academic Computing.
Unfortunately we have had to make the decision to terminate
publication. We have not and will not be charging your credit
card for the amount of the subscription. Your support is
genuinely appreciated. -Academic Computing.

This is a loss. Is there any hope of a replacement magazine?
For all the pros and cons it still represented a factor in the
the equation.
