The New Imperial Edition: Accompaniment CDs

(Boosey & Hawkes Voice). These collections of 30 songs each, released over 50 years ago, have been a mainstay of classical vocal study. There is a different song list for each voice type. Now accompaniment CDs are available that match each book. Special CD—ROM features are added to the audio CD which allow the tempo on the accompaniments to be adjusted without changing the pitch, or also, allow transposition.
