This app is a great tool for any serious ballet teacher or pedagogue. The creator has a variety of music, 2/4, 4/4, 6/8, 3/4, mazurka, polonaise, gigue, polka, march, waltz, adage, tango, etc., to work from. You can adjust the tempo, length, and introduction of each piece. The musician who recorded this music is also obviously talented. I especially enjoy the “info” portion of each selection of music that usually explains who wrote the music, when it was written, and where more info on it can be found. Incredibly educational for both the teacher and students!
