But the first question you should ask yourself
(1) when you are considering joining a choir is 'can you sing in

choir you apply to join is (5) free to want to audition you. Your voice
and technique will develop probably quite quickly with proper
instruction, and you may just end up wondering (6) why you didn't do
this years ago
