Even as a Classical musician, I find great joy in this book. Yes, saxophonists would do better to get the E-flat edition, since that was Parker's axe and everything works better. As a trumpeter, of course I'm using the B-flat edition, which sits very well for trumpet. In fact, the range requirements are so reasonable that long practice sessions on this music at the end of the day are not overly tiring. This book is a window into Parker's genius, and a welcome diversion from repetitive exercises or square etude books, because the music is very challenging and complex. Enjoy.
