Ben Paisner’s books on swing style are legendary. There are many many books from his catalogue, and qPress is going to publish as many of them as possible. This book is the sister publication to the treble clef edition, available right here.
This book is aimed at the intermediate level trombone players, and is a follow up to Paisner’s 30 Studies in Swing. Someone who has the facility to play more in-depth, technical, and involved swing tunes. Paisner gives great instructions at the top of each tune to let you know what to watch out for, and the tunes each have full chord changes to help you make sense of what is happening harmonically (and to play along with a pianist).
You should grab your horn right now and play the first two tunes for free in the samples. Then you can grab an immediate PDF download above.
