How much dance choreography is too much to add into a burlesque routine and how much is too little? I've heard burlesque dancers say "not too much dance choreography."
Formally trained dancers may have a tendency to think more about their choreography than their audience. In many rigidly choreographed dance routines, the dancer's focus is to the choreographer or to the other dancers; in burlesque, it is usually outward, to the audience. And often a trained dancer new to burlesque will merely dance, stop, and take off a piece of clothing instead of making the clothing removal playful, enticing, and innovative. It's not just what's revealed but the tease and play that leads up to the reveal that makes the costume removal worth watching.
A burlesque routine offers a unique opportunity to perform a striptease and/or combine glamour, mischief, and an arc. If the number doesn't take advantage of this, burlesque audiences might get restless and start texting during your number.
