I was wondering if anyone has an opinion about silicone/rubber molds that slide onto the bow stick to help train the hand into proper bow hold position. I never used one myself, but I am thinking of using it for some of my beginners. Also, how long is it appropriate to use the trainer?
Great question! I have used these in the past and they do work really well to help develop bow technique. I find that some students really struggle to place their bow hand in certain spots and these tools can really help. I suggest using the tools for up to 1 year, and try to not use it past that. Sometimes I’ve only used these tools for 1-2 months with students, and find that they are ready to take them off. The indicator would be to see how they hold the bow without the tools.
I’m not sure if this is a factor with the violin bow, but the bow grip trainer on cello tends to add a LOT of weight to the bow, which in turn tends to make playing very heavy handed. They’ve really helped a couple of my students, but limit their ability to do things like spiccato.
