Have you ever been a member of a choir?

Neither have I have you ever heard one?
Yes, its a body of singers who perform together.
What else can you tell me about a choir, have you ever wanted to be a part of one?
I have not but the term choir is applied to groups associated with churches.
That is true, most baptist churches have choirs.
They may sing without instruments but sometimes a piano is used.
probably to harmonize.
I like acapella due to it not having instrumental accompaniment.
