I'll just mention a technique that works for me ! As the routine is practiced over and over, I begin to notice cues in the music. The cues are more pronounced if the music is vocal. For instance, in the ensemble routine that I am part of, the music is from the movie " Rio ". A section of the music says---
" Let me take you to Rio-Rio,
fly like an eagle to Rio-Rio. . . . "
That section of music is where a long forward spiral is done. So when I hear that piece of music, I remember that the sequence is for forward skating to gain speed, left leg up so that the boot is touching the side of my right knee, then extend the left leg out to spiral position, with my arms holding wings extended out, and then hold still for the rest of the music phrase. Then the next music section " tells " me what is next. And so on, and so on. . . . This is how I remember, each piece of music tells me what I should be doing.
