Here we work on independence, one of the most interesting aspects of the drum kit. These exercises were influenced by those created by the drummer Kenny Arnoff. Watch out that the cymbal maintains one figure, the snare is in the 2-4, the hi-hat with crotchets and we read with the bass drum. Figures of one, two, and three beats. These exercises have helped me a lot to work on ambidexterity and all students of mine who have used them have been surprised with the results. Speed (crotchets) = 60 and (crotchets) = 70. Here we use the last semiquaver as a pattern for the cymbal. You will be able to see that this beat is difficult to execute while one reads the rest. As I commented before, these exercises are like a magnifying glass that enlarge where your problems lie. Whenever you come across such problems, try to eliminate them.
