“Well, You Needn’t” is a standard that could have only been written by Monk with an asymmetrical melody – unsettling and catchy at the same time – and chord changes that move in half step intervals. This tune can be a nightmare for anyone unfamiliar with navigating this kind of harmony. To develop your ear, listen to recordings of Monk, Miles, and Cannonball Adderley. Also, be sure to check out Jamie Cullum’s playful interpretation.
