It's completely free!
We are lucky as we don't just have a band room, we have our own band club, complete with air-conditioning, heating and a bar to purchase well earned refreshments for the break and after the rehearsal when some of our members sit and have a good chat. As the band has expanded we no longer fit in the actual band rehearsal room, which we now use for storage; so instead we use the main entertainment hall in the club. The club committee provides the band with the funds to buy new instruments, music, clothing and provide transport costs without there being any costs to band members.
