Pygmy music

The pygmy scale:

tones: 1/1 8/7 21/16 3/2 7/4
steps: 8/7 147/128 8/7 7/6 8/7

Also:

Scale: 1

LCM: 2^7*3*7^2

5 196 7/ 4 Harmonic Minor Seventh
4 168 3/ 2 Perfect Fifth
3 147 21/ 16
2 128 8/ 7
1 112 1/ 1 Unison

Minimum Chords:

1 84 4: 6: 7 1- 4- 5
2 168 21: 24: 28 3- 4- 5
3 336 14: 16: 21 1- 2- 4

I just couldn't resist the opportunity to do a short composition.

My fil5 utility expands this to:

LCM: 2^8*3^5*5^3*7^2

12 392 7/ 4 Harmonic Minor Seventh
11 336 3/ 2 Perfect Fifth
10 300 75/ 56
9 294 21/ 16
8 288 9/ 7
7 270 135/ 112
6 256 8/ 7
5 250 125/ 112
4 243 243/ 224
3 240 15/ 14
2 225 225/ 224
1 224 1/ 1 Unison

Minimum Chords:

1 84 4: 6: 7 1- 11- 12
2 126 14: 18: 21 1- 8- 11
3 168 21: 24: 28 9- 11- 12
4 180 9: 10: 12 2- 5- 10
5 180 15: 18: 20 2- 7- 10
6 210 5: 6: 7 3- 8- 11
7 336 14: 16: 21 1- 6- 11
8 1350 25: 27: 30 2- 4- 7

You can ftp the resulting composition from users.aol.com. (6,100
bytes.) CD to MMCKY and download the file pygmy.zip.
