If you play to a high standard, and can commit to weekly rehearsals and concerts, as well as to practice, come along and join in. 

There are no auditions, simply turn up in good time to the weekly rehearsals, at the beginning of a new programme (ie beginning of September or after the November concert), introduce yourself to the conductor and leader, and start making music. 

There is an annual subscription: £70 (£35 per term) for regular members, £50 (£25 per term) for senior citizens and £20 (£10 per term) for students/unwaged.
