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. Now, this is a somewhat complex figure. You are using three beats with a semiquaver pause at the beginning of each crotchet, which makes it necessary for you to adjust the beats very well, not to say sing, which is essential here. With some students, the exercise distorts into triplets, so be careful!
