Week 1: Harmony
Week 1 is all about writing to a harmony. A chord progression will be provided and its up to you to write a melody to fit. The harmony should be central to your piece, but not necessarily exclusive. You can branch out from it with counter harmonies, call-and-response, key changes, etc, but aim to keep your piece short. In addition to providing the progression, each day will also contain a style of music to emulate if you're looking for an additional challenge.
