This exercise consists of 3 parts, to be played with both hands (R-L or L-R) on the snare and combining this with the bass drum and HiHat. 1 - Practise triplets 2 - Practise quintuplets 3 - Practise septuplets. This is a very worthwhile exercise for control of this type of combination, since most drummers have difficulty in combining hands and feet in odd figures. You should dedicate as much time and effort as necessary to mastering these figures, since thorough assimilation will allow to make a lot of progress in your co-ordination of snare, bass drum, HiHat and cymbal. Quarter note = 50-60 In this type of exercise it is very important to work at slow speeds at first to control all the strokes and the co-ordination of hands and feet. Listen closely to the metronome so that you can read all the bars without having to stop. This takes some time to get used to. Be careful to avoid mordents. Be very exacting with yourself in your first steps. Then lower the speed by 5-point intervals until you reach 40. Once you have done this you can increase the speed until you reach your limit.
