Well, I've been asked to do something like that before but I simply don't have the time.
I spend my time playing my jazz gigs, writing and arranging music, teaching ensembles and giving private instruction. I'm getting a new degree in musical performance starting this fall and I still have to find some time to ride my bicycle and be with my girlfriend... I wish my days would have something like 48 hours then I could write a book! :D
I'm sure someone is coming out with such a book pretty soon. And I'll buy it for sure!
Thanks!
