New Imperial Edition Bass Songs Set Of 2 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.
