Before you sit in
Jam etiquette
- A1Use the sign-up sheet if there is one, and ask to sit in. If a bassist is already on the stand, ask: “Hey, is it cool if I play?”
- A2Don’t push to the front. In Will’s words: “Don’t try to always be the first one to play. Don’t kick anybody off especially if nobody knows you.”
- A3Time your walk. When Will hears the band “playing the head out of the song,” that’s when he starts making his way up.
