@Hanna_Brassheart, I was about to post the same thing @Annaliese_Dancemuddle did, just practice it slow, and work up to the original tempo... You can also just practice steps on their own, then add in all of the rest.
I am excited because this year I am going to re-try tap! I have been doing just Jazz for the last 6 years, but when I was 5-6 I did a duo tap and ballet class. This year I will do a jazz, tap, tech. and conditioning class, and possibly musical theatre!
