Hi-lo notation ~~was invented by [[Kite Giedraitis]]~~ 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.

== Notating chord progressions ==

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. ~~For example~~, ~~if C2 is~~ the tonic~~, A1 is loA,~~ A2 ~~is simply~~ A~~, and A3 is~~ hiA.

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.

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. See [[Kite Guitar Translations by Kite Giedraitis#Barbershop tags]]
