I'm a beginning cellist, and one of the things I struggle with is limb independence. The simple act of trying to keep a steady beat with my foot while playing subdivided beats (i.e. 8th notes) with my bow are too much for my beginner brain to handle. Naturally, my foot wants to speed up and tap on the 8th notes in synch with my arm, typically resulting in a very strange beat pattern with my foot that bears no resemblance to the actual beat.
Obviously there's all sorts of limb independence exercises for drummers, but many seem a bit complex for those of us who just need basic limb independence.
Has anyone ever seen any exercises for non-drummers or have other suggestions for building this skill?
