“SHIFT” HARMONY MODES

Also known as “Fixed Interval”, this takes the pitch of your lead voice and creates

harmonies a set number of semitones away, based on that pitch. The method of cre-

ating harmonies, using a fixed number of semitones relative to an input note or

pitch, is called chromatic harmony, the theory of which we'll go into later. 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.

VoicePrism has two harmony modes based on this type of harmony,

STEPPED SHIFT

and

SMOOTH SHIFT

allows the harmony voices to follow your input pitch, errors

and all, whereas

STEPPED SHIFT

jumps to the next appropriate semitone, kind of like pitch

correction on the shifted voice.
