I think it's arguable as to whether or not 12 eq is the "home base" tuning
of the blues. That tuning has been imposed by transcribers with a 12 eq
bias, but the early blues was not played from scores. The libral use of
pitch bends can easily be viewed as a method to compensate for instruments,
like guitar that were built to conform to 12 eq scales. There is very
little pitch bending used in other early examples of music with African
roots that are either a cappella, or played on instruments such as
non-fretted string instruments or wind instruments that are more flexible
in their intonation. This seem to indicate that the pitch bend was
initially used to correct the pitch, rather than used as a stylistic device.

I too have found a wide variety of musical inspirations, and at least
one of my compositions that I can recall right off was largely inspired
right from the start from a formal idea. Now it was not one of my most
successful compositions though.
