The following example moves between the snare drum and the three tom toms (usually just called toms). Notice the position on the staff of the notes indicating each of the toms. Use the left hand on the snare drum and the right hand on the toms.
Experiment with other combinations of the snare drum and toms. In the example below, the right hand plays the floor tom, while the left hand moves between the snare drum and the other two toms.
