Two musician friends of mine simultaneously have come up with similar uses for velcro. Bob, a horn player, designed his own mute holder using velcro strips and a large plastic drink cup. Start by gluing a strip of velcro around your cup. You’ll obviously need to find a cup that’s large enough to hold your mute. Not such a big deal for trumpet players, but probably impossible for tubists.
You’ll need enough velcro to next wrap around your chair. I imagine that it would be more comfortable to use the soft fabric-like strip here, since you’ll be sitting on it. Save the plastic hook portion of the velcro for use on the cup.
You’re all set. Your horn mute is right by your bell when you’re playing, making those quick mute changes much easier.
Coincidentally, a bassist friend of mine, Michael, was unsatisfied with using the bow quivers most bassists use if they alternate between arco and pizz throughout a performance or rehearsal. Michael needed a bow for one tune on a gig we were playing together and the bow changes happened a couple of times and were immediate. Since he mainly plays an older, slap-bass style on this tune he really couldn’t hold the bow in his hand when he wasn’t using it, so he used some velcro on his bow and the tailpiece of his bass to make for a very quick bow holder.
Keep in mind that he was using this for one tune and he doesn’t use his bow for gigs much at all. If you have an expensive bow and need to change a lot during your show I’m not sure how much I’d trust it to stay put. Use at your own risk.
What other musical uses of velcro can you think of? Off the top of my head, I was thinking that there might be a way to use some velcro to design an easy to reset method of holding sheet music on your music stand during outdoor gigs. I’ll have to give it some thought and see what I can come up with.
