Here we combine intervals with the drum beat. You already know the intervals, now let's see the percussion. We'll be using kick, snare, and a few extra hits, let's say tom-toms. I'm starting with an upper kick because I have to play an interval. Then, I move to a lower kick and snare. After the snare, I play 2 toms, first with a thumb and middle finger. Try to play toms a little bit softer and quieter, they should sound more like an echo effect.
Moving to the 2nd interval, the rhythm stays the same, 3rd too. And on the 4th interval, there is a small drum fill: snare tom snare snare tom. I'm doing an accent on the last note, a percussive pop to make a more aggressive sound. Think about dynamics when performing drums. The more dynamics you have, the better it will sound.
