Tutorial or practice mode to learn dance moves

I'd like to see a mode where you can learn each movement in the game. Additionally, would like to see the ability to practice each song or section of song similar to that of the DDR games on PlayStation. There was a practice mode where you could see all the movements of the song in order, and can select a start and stop point to practice that part of the song. There was also the ability to slow the song down a little bit and add beats or clap track.
