This unique aural training method was developed In response to requests for more teaching materials based on the popular choral ensemble solfege book Choral Ensemble Intonation. It gives choirs ear training exercises in all modes, each exercise providing a rich harmonic syntax to facilitate the learning experience. For each mode, this one-of-a-kind resource includes exercises for intonation in the mode, intervals within the mode, modal tuning exercises, and a modal choral example. In addition, a CD of full accompaniments is provided to use as a classroom supplement. These exercises should be used in preparation for the music to be rehearsed, as part of the choral warm-up.
