Query: Brilliant!

This is exactly what I had been looking for, for ages.It contains demonstrations by professional ballet dancers of every movement in ballet along with an audio explanation of how to perform the movement. The most difficult movements are repeated in close-up, and, most of the time, in slow motion.I also enjoyed the examples of enchainements combining all the movements at the barre, linking steps, centre, pirouettes, adage, allegro, batterie and pointe work.It is a must for teachers and ballet students.Furthermore, they present the main differences between the Russian, French an Cecchetti styles.Enjoy!
