One important thing I neglected to mention yesterday about memorizing choreography:

I think it’s very important, when memorizing a dance sequence, not to get too locked into dancing the sequence to one particular song.

Couple of reasons. You want to be able to bust out your amazing moves to a variety of songs so you have more chances to perform, no matter what the DJ is playing. Also, if you rely too much on the song to remind you what comes next, then you won’t be as likely to pull out bits and pieces of choreography where and when you need them.

Plus, you can actually use songs with different tempos to help you learn sequences. Here’s what you do:

• Put a little practice music playlist together for yourself. All the songs should have a very reliable structure, just four eight-counts throughout, without long intros or weird bridges or tempo changes. The songs should range from ridiculously slow to crazy fast, with lots of variety in between.
• Sort them out by order of tempo. Here’s a handy little free metronome – you just tap along with the music while it’s playing to figure out the BPMs.
• Now, whatever piece of the choreography you’re working on, simply practice it to each song on your playlist, starting with the slowest one and working it up faster and faster.

Simple idea, but I’ve found it to be amazingly helpful!
