Hi Cadenza,
Do you know the different types of traditional Cuban music the science major/musician examined? Was it specifically rumba? What do you mean by "the ambiguous root of clave?" I can understand the term
ambiguous being applied to particular performances of clave, but not the structure of clave ("root?").
Computer analysis of clave performances certainly reveals subtle nuances. Congaboard member James has a great webpage on the subject:
http://rumbaclave.blogspot.com/What Mike Spiro has aptly dubbed
fix is found in North American jazz, Cuban rumba and Brazilian samba. However, there are also examples of "straight" triple-pulse and duple-pulse musics in Cuba. Iyesá for instance. Also, there are plenty of "straight" rhythms in Africa itself.
The rumba aesthetic is one particular rhythmic approach within myriad clave-based rhythms. To me one of the most extreme expressions of the rumba aesthetic is the arrangement in some Matanzas columbias where both the 4/4 cascara and the 6/8 standard bell pattern are played simultaneously. I have yet to encounter an African analogue to that extreme use of simultaneous triple and duple-pulse strokes.
As far as writing the music in Western notation, many musics have subtle nuances in their performance that are only approximated on paper. It is understood that the written music has certain inherent limitations. If a professional pianist were to perform Chopin strictly as written, with no "feel," it would be considered a sterile performance.
The same is true of course in the performance of jazz, where professional musicians who rely heavily on reading also understand the unwritten "feel" required to play the music correctly.
I think I’ve mentioned this before, but African musicians do not have a problem with writing their music down. To quote African musician/scholar Dr. Kofi Agawu:
"It is noteworthy that the debate about the appropriateness of staff ["Western"] notation for African music is a subject of particular interest to outsiders, not insiders. African scholars from Kyagambiddwa to Kongo have for the most part accepted the conventions - and limitations – of staff notation and gone on to produce transcriptions in order to inform and to make possible a higher level of discussion and debate" (Agawu 2003:52).
That said. I can appreciate how you have had to "relearn a lifetime of musical teaching." This musical journey continues to challenge me. The subject of "fix" and related "feels" is indeed fascinating.
