  • Page 34: Shift" Harmony Modes

    We con- sider shifting to be non-intelligent harmony because VoicePrism is not set to any par- ticular key or scale. These are pure, parallel harmonies. The most common shift har- mony voices are the 5th (7 semitones) and octave (12 semitones), ranging from two octaves below the input to two octaves above the input pitch.
