I just found out that Godfried Toussaint died while at a conference in Japan this past July.
Another pioneer is gone. His main contributions were in the field of pattern recognition.
I'm posting this here partly as a follow up to Rick Cohn's recent question regarding teaching rhythm & meter. I'm not at all sure how many appreciate or take advantage of (or even know anything about) Toussaint's contribution to a theory of maximally even rhythmic structures (which he conceived of as 'Euclidean rhythms' - a distinction without a lot of difference) that extend Clough, Douthett et al's contributions in max even sets which, due to C&D's nomenclature (hyperdiatonic, etc.), seem to be taken mostly as pitch scale theory. The abstract interval-string math supporting both pitch and rhythm applications is identical.
He wrote a book, The Geometry of Musical Rhythm, that, in my opinion, is flawed by trying to connect Euclidean rhythms to what makes a 'good' rhythm good. A more straightforward introduction to his work is here:
'The Euclidean Algorithm Generates Traditional Musical Rhythms'.
