The importance of live music for ballet and dance training cannot be overemphasized and this collection of forty works by Frederic Chopin is enormously useful to the rehearsal accompanist. The pieces have been broadly divided into two: pieces for exercises a la barre and a la terre. Then there are further subdivisions into the specific movements which the works are meant to accompany: plié relevé pirouette and so forth.The pieces and excerpts chosen would suit the upper-intermediate pianist.
