This was an amateur chamber coir, that started as a quartet, but had about 12 member for most of its one decade long existence.
We had rehearsals 2 times a week, 3-4 times before important concerts. The choir was democratic, anyone could bring music pieces or even event invitations, and the chour discussed, what events, what songs to do.
The repertoire was diverse, and fairly balanced - see some records on the left. We sang in pubs, funerals, weddings, city events - as Kodaly said, music belongs to everyone.
