Hank Edmond’s Jazz Beats Volumes 1 & 2 is a collection of 100 pages of duets for trumpet, horn and all treble clef brass in the jazz idiom.
Hank was a prolific transcriber, and he has books available for many areas of jazz music in particular. This book, though, is original, duets inspired by classic jazz themes, progressions, and melodies, and turned into something brand new in duet form for two intermediate to advanced players.
These books are gold, and getting the two book set above at a discount is your best bet. I have included the tune lists from each book as well as lots of samples to the left. Try them out before you buy. Enjoy!
