The Harmony Director lets you demonstrate to your students how their individual notes fit into complete chords. It allows you to teach them through examples rather than words alone, the kind of harmonic understanding that takes many years of experience to develop. The Harmony Director can help your ensemble move from good to outstanding. 

There is certainly an art to ear training... & this comprehensive tool brings harmony training, rhythm training and ensemble timing together in one convenient device. It enables music educators to clearly demonstrate pure temperaments and for students to learn how to tune individual notes within chords, so that entire chords may be tuned. The HD-200 Harmony Director helps musicians understand how each part fits into the complete harmony of the ensemble. This level of understanding will help your ensemble move from good to outstanding.

Easy Operation: Part of the HD-200's power is its ease-of-use and friendly interface. With two LCD screens and intuitive “one touch” operations, the HD-200 empowers educators in teaching intonation and ensemble timing to high levels quicker than conventional means.
