A player also needs to learn the music, the styles and thoroughly know the content and repertoire. Most importantly, the successful player knows how to get along with the other members in the band. They also have a back-up instrument in case of emergency.
Better yet, each player in a band, trio or group situation should learn enough material to cover a whole night by themselves. Yes, that’s right each player needs to have a whole night of music ready to play. The other members need to learn the tunes as well. So, 4 members equals 4 whole song lists that every other member is completely familiar with as well.
Teach every member in the group your songs and learn theirs. Why?
What if a member or two fails to show for a gig? You already got it covered. Right? No worries. The show must go on. And successful musicians prove it will.
If you want to get asked back to a venue, then do a good job. Show the boss you can handle any situation that arises. Successful bands deliver the goods-always!
