Okay, some may recognize this.  Some may not...  This is a 'dance studio' that has instructors with such lessons as:

BBBJ - Basic Black Ballroom and Jazz
GFE - Good Friendly Entertainment
DATY - Dancercise and Tap Yourself

I understand about those activities... But I'm confused about the following.  Can anyone help me out with these?

1] The 5 Basic Positions of Ballet
2] Step-by-step Alignment and Points
3] How to Hold Your Hands
4] Head Position and Gaze
5] Positions of the Arms

Thanks.
