The Groove & The Feel
Ornithology is almost always played at a fast swing tempo. The rhythm section must provide a rock-solid, driving pulse that never wavers.
Improvisation Strategies
Soloing over 'Moon' changes requires a strategy built on 'cells' and patterns. Because the chords move fast, you must think in long, linear phrases.
