My, this must be a good thread - already we have controvery.
I must admit, when I suggested this thread , I had in mind jazz music (of any sub-genre), presenting samples of indigenous jazz.
However, I obviously havent thought it through too well, and who am I to prevent Forum members from handling the subject as they wish
with my blessing.
An individual comment to J.W. (Hi John, its good to have you back).
Its true that jass developed in the States (New Orleans to be precise) but even then its roots are partially derived from the parts of the world
from whence the originators stem. Africa mainly of course but Europe too. (Think Cajun and more lately, Latin America.)
Yes, when jazz extends to other countries there is inevitably going to be many similarities to American jazz music, (in its many forms).
However when researching for the thread (via Youtube I admit) it became apparent that differences do occur and National characteristics
do creep (or in some cases jump) in.
Finally, you use the term "spontaneous improvisation" and I am sure this is still important in solo contributions. But when it comes to many jazz
productions, you will notice the reference to "arranged by" which applies to most of them. Enough said.
