Hi-lo notation | Hi-lo notation is for naming chord voicings. It applies to all tunings, even conventional ones like 12-edo or meantone. It allows arrangers, composers and theorists to discuss specific voicings with much more accuracy than the conventional 1st inversion, 2nd inversion, etc. nomenclature. | ||

There are sometimes two possible names for a voicing, depending on what one considers the "home octave" to be. As we saw, C C E G can be either CaddloR or Chi35add8. This ambiguity can be removed by designating one note in a specific octave as "the" tonic, then naming all other notes relative to that tonic. | There are sometimes two possible names for a voicing, depending on what one considers the "home octave" to be. As we saw, C C E G can be either CaddloR or Chi35add8. This ambiguity can be removed by designating one note in a specific octave as "the" tonic, then naming all other notes relative to that tonic. Unlike [[wikipedia:Scientific_pitch_notation|octave numbers]] which only increase when going from B up to C, the hi-lo categories only change in the region of the tonic. This has the advantage that transposing to a new key won't change the hi-lo categories. | ||

Chord progressions can be written out as e.g. Cadd8 - loAmhi3add8 - Dm7 - loG7hi3. The entire 4-part harmony can be deduced note-for-note from this. Here are the notes, where the lower octave uses underlined letters and the upper octave uses lower-case letters: | |||

Naming the roots as hi or lo ''almost'' allows us to reduce a barbershop tag to a mere succession of chords. However voices sometimes coincide or cross.
