15 against 16 Polyrhythm (Exercises like this one keep my brain very happy)
[warning] This is an exercise …… it is not suppose to be musical [/warning]
I have developed a method that will make you look at rhythm within time for what it truly is and will give you all tools necessary to get you to a much higher professional level. Download my book “In-Depth Rhythm Studies” and by working on it you will have all the doors open for you.
15 against 16 …. cool …. but why? Because I can is one of the answers but to me this is a physical and mental exercise to gain more freedom. Being able to play what I feel benefits a musical situation I end up in without having to think about twice.
It is very simple. It is like magic, once you know how, it is not as cool and impressive.
Start by playing 3 against 4 between your feet. 3 with your hi-hat and 4 on your bass drum and get very comfortable with it.
Great. Now play the exact same 3 against 4. Group your “3 part” of the polyrhythm by four notes and count it in your head as 4. Get very comfortable with it.
Now add snare drum playing 5 against your new 4. (3 part of a (3 against 4) polyrhythm grouped by 4 notes). The original 3 against 4 in your feet should be fully automatic (muscle memory). Counting will help your ears better understand what’s going on and eventually set your mind to comprehend the “new” 4 and your snare will just play the 5 against it.
The last step is very simple in principal ( yet the most difficult ). Do not play the 3 part of the original 3 against 4 polyrhythm and you end up having precise 15 against 16 polyrhythm.
