An easy and efficient way to begin each rehearsal. Twenty sequences, each consisting of four components (warming down, warming up, diction, and chordal), prepare the voice and the mind for producing a beautiful choral sound. The director's edition contains all the vocal parts and piano accompaniments in addition to a detailed introduction and user's guide. The singer edition, which includes the vocal parts, is octavo size, designed to fit comfortably in choral folders all year long. An accompaniment CD is also available.
