I often make up beats (as you described) and tapping them on my thighs, etc. I also often make up tunes and hum or whistle them, imagining others accompanying me. Would you say that your tapping is a stim?
I love Steve Reich's "Clapping" (

I just recently read an article, that I can't locate right now, about change-ringing (church bells, campanology) and the mathematics of permutations that underlie the changes (see
http://en.wikipedia.org/wiki/Method_ringing for a brief explanation).
I use short sequences with prime lengths to create long and evolving music without any repetition, either rhythmically or melodically. Restriction to a pentatonic scale makes for quite harmonic compositions.
