This is not really a 4-dimensional cube, but a mere triangle. This is the table of [[tetrachord]] species in [[31edo|31-edo]], i.e. all of the ways that a perfect 4th (13 dieses) can be broken up into three steps. Numbers indicate intervals in degrees of 31.

===Pick an ostinato===  
===Pick an ostinato===
Have a rhythm and generalized contour that you use on each tetrachord. Using the 7-note scale made up of 2 "disjunct" tetrachords (separated by a major tone), my ostinato was 0-1-2-3-2-1-0-1-2-3, 4-5-6-7-6-5-4-5-6-7, 0-1-2-3-4-5-6-7.

===Pick a path===  
===Pick a path===
I prefer a path that is complete (hits every square exactly once) and incremental (moves by exchanges of a single diesis; in the chart, single moves of up/down, left/right, or northeast/southwest only). The path used in the first recording begins at the upper-right of the chart and zigzags left-right-left-right to the bottom left. Another fun path yet untried is a spiral triangle.

Start out just humming or singing along to the recording. Use the unretuned MIDI file if you want to change the tempo. Ask me for more renderings on my synth with different specifications, and I will make and upload them. I might add more renderings out of my own explorations too.

Have a rhythm and generalized contour that you use on each tetrachord. Using the 7-note scale made up of 2 &amp;quot;disjunct&amp;quot; tetrachords (separated by a major tone), my ostinato was 0-1-2-3-2-1-0-1-2-3, 4-5-6-7-6-5-4-5-6-7, 0-1-2-3-4-5-6-7.&lt;br /&gt;

I prefer a path that is complete (hits every square exactly once) and incremental (moves by exchanges of a single diesis; in the chart, single moves of up/down, left/right, or northeast/southwest only). The path used in the first recording begins at the upper-right of the chart and zigzags left-right-left-right to the bottom left. Another fun path yet untried is a spiral triangle.&lt;br /&gt;

Start out just humming or singing along to the recording. Use the unretuned MIDI file if you want to change the tempo. Ask me for more renderings on my synth with different specifications, and I will make and upload them. I might add more renderings out of my own explorations too.&lt;br /&gt;

This is not really a 4-dimensional cube, but a mere triangle. This is the table of tetrachord species in 31-edo, i.e. all of the ways that a perfect 4th (13 dieses) can be broken up into three steps. Numbers indicate intervals in degrees of 31.

11-1-1 10-1-2 9-1-3 8-1-4 7-1-5 6-1-6 5-1-7 4-1-8 3-1-9 2-1-10 1-1-11
10-2-1 9-2-2 8-2-3 7-2-4 6-2-5 5-2-6 4-2-7 3-2-8 2-2-9 1-2-10
9-3-1 8-3-2 7-3-3 6-3-4 5-3-5 4-3-6 3-3-7 2-3-8 1-3-9
8-4-1 7-4-2 6-4-3 5-4-4 4-4-5 3-4-6 2-4-7 1-4-8
7-5-1 6-5-2 5-5-3 4-5-4 3-5-5 2-5-6 1-5-7
6-6-1 5-6-2 4-6-3 3-6-4 2-6-5 1-6-6
5-7-1 4-7-2 3-7-3 2-7-4 1-7-5
4-8-1 3-8-2 2-8-3 1-8-4
3-9-1 2-9-2 1-9-3
2-10-1 1-10-2
1-11-1

Pick an ostinato

Have a rhythm and generalized contour that you use on each tetrachord. Using the 7-note scale made up of 2 "disjunct" tetrachords (separated by a major tone), my ostinato was 0-1-2-3-2-1-0-1-2-3, 4-5-6-7-6-5-4-5-6-7, 0-1-2-3-4-5-6-7.

Pick a path

I prefer a path that is complete (hits every square exactly once) and incremental (moves by exchanges of a single diesis; in the chart, single moves of up/down, left/right, or northeast/southwest only). The path used in the first recording begins at the upper-right of the chart and zigzags left-right-left-right to the bottom left. Another fun path yet untried is a spiral triangle.

link ostinato path range tempo

(mp3 midi)

0 1 2 3 2 1

0 1 2 3

4 5 6 7 6 5

4 5 6 7

0 1 2 3 4 5 6 7

zigzag from 1-1-11 Fd2 - Fd3 eighth = 92

Go!

Start out just humming or singing along to the recording. Use the unretuned MIDI file if you want to change the tempo. Ask me for more renderings on my synth with different specifications, and I will make and upload them. I might add more renderings out of my own explorations too.

Extra credit

Sing the entire exercise with the shortspeak interval names. This chart should help:

Next-assignment assignment

Write a ditty in a specific or generalized tetrachord scale, and turn it into an assignment for me.
