The HD-100 Harmony Director from the Yamaha Band & Orchestral Division, is designed to help young vocalists and instrumentalists understand how individual notes fit into a chord.

The HD-100 Harmony Director is a 49-key tuning device that resembles a small keyboard. It teaches students to tune the notes within actual chords, providing an aid to improve intonation, harmony and overall sound.

The HD-100's 10-preset temperaments include pure, major and minor scales, meantone and Pythagorean. It will tune every note to the right pitch for any given scale and key, and each of the 12 notes of the octave can be assigned its own pitch and volume settings. They can then be saved to user memory, and a transposition transposition /trans·po·si·tion/ (trans?po-zish´un)

The HD-100 also allows for any tempo to be "tapped" in, to ensure rhythmic precision. When playing a song with a key change, the HD-100 will automatically detect the change and alter the pitches of each note to fit the new key. The MIDI-compatible HD-100 features easy-to-read LED and LCD displays and a data entry dial to make input quick and easy.
