Some I-IV-V Progressions in 16 equal

Sunday, August 4th, 2013

To avoid confusion
1. All of the notation is in scordatura. If your regular midi controller is tuned to play 16 edo you will get the sound of the chord progressions if you play the 12 equal notation. Consider it a transformation in tuning.
2. When I talk about scale degrees, such as referring to I, IV, or V, or a fifth or third, I am relating the structure in 16 edo to the function in 12 equal for the sake of being able to discuss something which does not have a widely know naming conventions. When, as I plan, start using progressions ambivalent or foreign to 12 equal this naming convention will have to be expanded. For now just consider it a way to get ideas across.

Note: all of the music is presented as scordatura – if you tune your midi controller to 16 notes per octave and play the notes shown you will hear the example progressions.

Tonic in root, 2nd inversion functional IV, tonic in root


Major Cadence 1


Tonic in root, functional IV in 2nd inversion, tonic in 1st inversion


Major Cadence 2


Tonic in root, functional IV in root, tonic in 1st inversion


Major Cadence 3
