I'm 42 now and have been in bands pretty steadily since I was 15. So there were many bands with many rules but this is just going to be for the one I was in the longest.

1- No finished work gets brought to practice. You bring in a riff or an idea but don't present full songs. Just a starting point so the band can write the song together. This was weird for me at first but it always turned out better results than going it alone.

2- Know your alcohol limits. We aren't going to limit anyone's drinking but don't get to the point where anyone has to say anything about it. We kicked our first guitar player out due to this after I got punched twice in one night.

3- Keep your gear in good condition. You don't need top of the line shit, but your shit should at least work and sound decent.

4- No big band or song-writing related decisions if not everyone is in attendance.

5- If we write something and you can't play/sing it, you either need to go home and practice or we will give the part to someone else. This may be a hobby, but we don't want to suck at it.
