Do Nothing Line Counter Line Etude by Tony Miceli
Check out this etude. It's playin over the tune 'Do Nothing 'til You Hear From Me'. It's a 2 mallet solo however it's a melody and an accompaniment. It's really important to be able to make harmony work in the simplest way possible. Ultimately can you play a single line and outline the harmony of a tune? If you don't understand think about the Bach solo flute, violin and cello sonatas and partidas. Study them and you'll learn a ton about bebop.
Anyway, here's me playing an etude and below is a PDF of one you can work on.
