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
Pitch Number in 12EDO | Octave Clamped Factor in 12EDO | Pitch Number in 16EDO-math | Octave Clamped Factor in 16EDO-math | Pitch Number in 16EDO-ear | Octave Clamped Factor in 16EDO-ear |
0 | 1 | 0 | 1 | 0 | 1 |
2 | 1.1225... | 3 | 1.1388... | 3 | 1.1388... |
4 | 1.2599... | 5 | 1.2419... | 5 | 1.2419... |
5 | 1.3348... | 7 | 1.3543... | 6 | 1.2968 |
7 | 1.4983... | 9 | 1.4768... | 9 | 1.4768 |
9 | 1.6818... | C | 1.6818... | C | 1.6818... |
B | 1.8877... | F | 1.9152... | E | 1.8340... |
C | 2 | X | 2 | 0 | 2 |
16EDO in 2D
by using keybOwOard 2D : https://memo2007ultra.wixsite.com/m27u-m2016/keybowoard-2d
setting EDO=16, edoX=9, edoY=5, and invoke 2D-edo
you will have the following layout
F81A3C5E
A3C5E709
5E7092B4
092B4D6F
we can also slightly achieve the 4 octave clamped factors in Shasavic Music
Factor | Octave Clamped Factor | Note Number in 16EDO | Note relative Position |
3 | 3/2 = 1.5 | 9 | r |
5 | 5/4 = 1.25 | 5 | u |
7 | 7/4 = 1.75 | D | rrd |
11 | 11/8 = 1.375 | 7 | rru |
to play all the harmonics (1f,2f,3f,4f,...,16f)
