Query: Dance class in a box!

My daughter, who is too shy to face a class of peers just yet, adores this video and wants to "do her class" at least once a day, much to her twin brother's chagrin. I've really seen her picking up on the technique and form over the months, and her flexability has increased dramatically. The lyrics beautifully ingrain the moves and methods in her mind as she relaxes and enjoys feeling so pretty. After the girls practice a step, a profesional ballerina is shown performing the move, often with a partner. My daughter calls her brother over at that time to lift her and he obliges, heaving her an inch of the floor with a heavy grunt.
