Chapter Four: Pitch and Notation Charts

Even when things are going well, the notes are never good enough. –Mike Ellison on 12-eq

All things are arranged in a certain order, and this order constitutes the form by which the universe resembles God.  —  Dante on 53-eq?

In this chapter we are going to lay out in detail the practical specifics of setting yourself up to be functional in a 53-eq template. Here are what the 53 pitches of 53-equal sound like relative to C. I include an mp3 file of all 53 notes against Middle C, so you can compare the pitches you end up with to what I have. This chapter also has a very detailed chart of the many musical meanings of all 53 notes. It’s a lot of fun to just listen to this mp3 file of the 53 notes against C. When does the “minor third” interval start sounding like the “major third,” and when does that start sounding like the “perfect fourth”?
