Overtone Tuning (C.E.G.A#.C.D)

Built from the 4th through 9th partials of the harmonic series, the overtone tuning is highly compressed - all six strings fall within little more than a single octave. This causes some very tight chords and densely packed clusters of notes. Accordingly, the chord chart emphasizes intervallic chords such as the pandiatonic forms. Many of the major, minor, and seventh chords have repeating tones, which adds an interesting kind of chorus or depth to the sound. The tuning sounds like a "soprano twelve string."
