"How to Create Jazz Ad-libs from Lines: Packed with know-how to turn humming or melodies vaguely floating in your head into ad-lib solos!" Katsuhiro Kado Price: ¥2000 + ¥2000 + ¥2300 = ¥6300 (excluding tax) "The Rules of Ad-lib" shows some signs of use, but the other two books are almost new. I used them for practicing saxophone ad-libs. Especially "The Rules of Jazz Ad-lib."
