I OFTEN CREATE BEATS WITH MY TEETH.
for the snare, i hit my two left incisors together. for the kick, i hit my two front teeth against the bottom four. i've done this for as long as i can remember. sometimes i add in a little syncopated breathing for a hi-hat effect. and i probably look slightly strange when i do this. and i'm not sure why i'm telling you about it. it's just something i do.
