Advice from Mikko Nissinen
Mikko Nissinen is Artistic Director at Boston Ballet and was on the judging panel at the competition in Toronto. We should probably listen to his advice.
The best advice I ever received:
Listen to the music with your inner ear, and become the music.
The advice I would pass on:
Be sure the basic standing working position is correct, with weight forward. This will allow you to release forward, side, back, to any direction, and will allow freedom in everything you do. That basic foundation is key.
