I have learned part of the French counting system (crotchet=Ta, crotchet rest=Sa etc.). Where can I find the rest of the system? I've spent hours searching and have found more questions than answers.
Seems like Zoltan Kodaly is the perpetrator. Hungarian, not French. Look him up, and I think you have what you need.
EDIT - further investigation leads to 'French time names', sometimes accredited to Galin - Paris - Cheve system. Using such as 'Ta-a-a-a' for semibreve (full note), 'Ta-a' for minim, 'Ta' for crotchet (1/4), down to 'Ta-fa-te-fe' for 4 1/16th notes (semi quavers). Similar, but not identical to the above mentioned - and, yes, French. I remember using it in the '50s/'60s in music lessons, briefly.
