Intermediate level. These hip, swinging etudes in the swing/bop style are a great source for blues and bebop licks and fun to play! Lennie wrote these specifically to be played with the tracks from Jamey's Vol.42 Blues In All Keys. There is one complete solo (etude) for each of the 12 keys and 12 tracks. This book of solos is also great jazz sight reading material, since it contains all of the most-used jazz rhythms and syncopation you'll ever encounter. Perfect for Learning your way around The Blues - even in the tough keys!
