As a music teacher and professional musican I was hoping to have this text be an aid to my students. The printed music is clear, although the arrangements are not necessarily the best, particularly with regards to the 4/4 meter as opposed to the true alla breve. The cd that is included is a nice bonus, but it would have been nice to hear real instruments on the tracks instead of a synthesizer. The dance instructions are somewhat unclear. I had to refer to two other resources just to decipher what is meant. So, this is an average product, not to be trusted as a vailid source standing on its own.
