Each Music Minus One set includes printed music and a CD. The printed music is of the solo part only, piano parts are not included. The CD contains recordings of the solo & accompaniment together, as well as the accompaniments only. Some selections may have slower tempo performances for pieces that present a more complex technical challenge. The accompaniments were recorded with the pianist listening to a playback of the complete performance. In this way, the tempo, phrasing, and subtle nuances of the soloist were re-recorded. A printed copy of the solo part is included with cues and rhythmic notations. In addition, a performance guide with comprehensive tehnical advice, personal insights and musical illustrations is presented by the soloist for each selection. Listening to the accompaniment while following the solo part will give a better sense of ensemble and understanding of the music.
