I've been working on some exercises and a full barre all focused on Epaullement! Here is one of the combos from the series.
1: (right foot) Ball
2: pointe - look over the shoulder
5-8: repeat on the left foot
1-4: Snake (demi plié, forced arch, stretch legs, lower heels)
5-8: reverse snake (elevé, plié, heels down, stretch legs.)
Repeat with the head going under instead of over.
Repeat the whole combination with the head over and under, but add a plié to the point (count 2 and 6).
To finish: elevé and balance.
