It don't mean a thing if you haven't played this chart yet! "Fantasia on an Ellington Theme" is a warped (but still swinging!) interpretation of one of Duke Ellington's best-known tunes.
"Fantasia" is a bang-for-the-buck chart: it is scored to work with 3 or 4 horns, with all necessary parts provided. There are also enough alternate parts to give you the flexibility to mix-and-match with your available horn players.
