Using linear drumming (the ‘one beat – one sound’ style) we can practice limb coordination in many ways. We can design simple schemes on the set (circles, x, squares etc) defining schemes that help us to develope independence, coordination and timing.
A first, simple, set of exercises is Linear drumming circles: 4 sounds (one for each limb), a circle played clockwise and counterclockwise where sounds shift from pattern to pattern. A good practice to help our brain to coordinate all those stuff
