This lesson is all about the basic independence a drummer's limbs should have in order play basic rhythms without any problems. It also helps to improve timing of the individual limbs in relation to each other. These exercises can be extended and changed as much as the drummer wishes.
This particular lesson is extremely useful for drummer that have just started out playing, but may drastically improve an advanced drummers' independence and timing as well.

These exercises are based on the ones I was taught by my teacher Luuk Kranenburg when I had just started out playing in my early teens. Credit where credit is due!
