IF YOU BREAKDANCE PLEASE HELP ME!! I have been working on windmills for a while now and I can’t seem to stay in on place I kinda just move around everywhere while doing them. Any tips on how to fix that?

Try wearing gloves or gripped shoes, or clothes that aren't too big but just your size, you'll feel lighter, and a lot more comfortable while doing them and you'll  learn so much quicker feeling comfortable and relaxed while breakdancing at the same time!

Explanation:

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
