Anyone work through this book? It's mainly Bergonzi's take on the Bebop scale, with tunes derivative of Bebop tunes such as Blues For Alice, Joy Spring, etc. For minor key tunes, he uses IV7b9b13. Any idea as to why he prefers this to an altered dominant? No lowered 5th or raised 11th? Apparently he's preferring The Harmonic Minor scale?
For example, he's got Cm69 Bebop scale, leading to F7b9b13. Why?
