So I have been offered to join a band and I have accepted. I will be the youngest there. And I am very nervous.
man age is nothing! I play in a church band where everyone is mid- late twenties, and have been playing for many years. we had to get a substitute drummer for the one practice and the guy we managed to get was about (not lying) 10 years YOUNGER! Grade 10 or something...
Let me tell you, that guy proved that age is nothing when it comes to music - he jammed better than most guys twice his age! - if you know your instrument and play with confidence (in that knowledge of knowing your instrument & music) you'll be fine!
Good luck, and most important - ENJOY it! ?
