16EDO

What it is ?


take an octave and cut it into 16 notes, this is 16EDO or 16TET



Shasavic Music Theory - by LampLight


In Shasavic Theory by LampLight, the desired target octave clamped factors are as follows :

  • 3f -> 3/2 = 1.5

  • 5f -> 5/4 = 1.25

  • 7f -> 7/4 = 1.75

  • 11f -> 11/8 = 1.375


here is a video from LampLight explaining Shasavic Music if you are completely new to this :



How "good" it is


I made a tool to measure how "good" an EDO/TET is, the lower the distance, the "better" it is

assume that the desired target octave clamped factors are 1.5, 1.25, 1.75, 1.375, 1.625, the the following screenshot is the result :

can I play a Major Scale on 16EDO ?


yes ... sort of ...

the Major scale is heavily derived from 12EDO.


if we use Math, we can have the following :


2^(p/12) = 2^(P/16)

p/12 = P/16

p / 12 x 16 = P


where p (smol one) is the note we want in 12EDO

where P (beeg one) is the note we need in 16EDO


here we can try all p = 0,1,2,...,11

but we can also limit p to be the MajorScale notes (0,2,4,5,7,9,B)


note : here, for numbers between 9 < x < 16, I will be using ABCDEF where A=10


I also tried to play the Scale by ear


below is the comparison between 12EDO, 16EDO-math, 16EDO-ear

16EDO in 2D


setting EDO=16, edoX=9, edoY=5, and invoke 2D-edo

you will have the following layout

we can also slightly achieve the 4 octave clamped factors in Shasavic Music
