just wanted to recommend a choir:
www.bristolplaysmusic.org.uk/young-people/joining-a-band-or-orchestra/west-bristol-music-centre/
It is not well advertised. It's in the middle of Southmead ( there is a music school there). It's very little group ( 3-4 kids kids). It's free and it's like a private singing lesson.
The teacher is a young guy who is very enthusiastic, funny and has got a great approach.
The rehearsal is quite informal:
they do lots of stretching, breathing, funny noises, a bit of etiquette, matching pitch - all as games.
Last Monday they sang two easy to learn songs (with a guitar).
It is all great fun and my daughter loves it.
It's 4.30-5.15 every Monday in West Bristol Music Centre, at Stanton Road ( it's signposted)
