I am playing background music
Technically, the “Christmas Season” begins on Christmas Eve.
I’m a bit late, but there’s always next year…
For a performance in an adult day care center on 12/29, I used an arrangement by Bird/Peters
I just ask the hosts what they want. I have a New Year’s Day gig every year and it’s her holiday party so she wants holiday music, for example.
If you are looking to move outside the holiday mindset, the answer is whatever you normally play.
