The Scales

 

Harry Partch and A Genesis of a Music

My music is based on a set of hexad's derived from A Genesis of a Music, Harry Partch's well written and influential book on his musical philosophy. Go to a library, check it out, and read it.

The scales I use are derived from Harry's Diamond Marimba. I take scales up and to the right, as in 1:1, 5:4, 3:2, 7:4, 9:8, 11:8 or down and to the right, as in 1:1, 8:5, 4:3, 8:7, 16:9, 16:11. For convenience, I have renamed the ratios as note names and accidentals. C is 1:1, E is 5:4, G is 3:2, D is 9:8, A++ is 7:4, and F++ is 11:8. Each note in the diamond has a note name, which is used in the macro source code. Harry didn't use consisten note names or accidentals for all his compositions; he made notation for each instrument to make it easier for musicians to play it. I don't have any musicians playing my music, so I chose a notation system based on Erv Wilson's note names and accidentals.

The Note names I use are these:

                           F++
D+ D-
A++ Bb B-
G F# G G#
E E-- D# E++ E-
C C C C C C
Ab A- A+ G++ A--
F Gb F E+
D++ D D--
A# B--
G--

In ratios, it looks like this:

Some day I'll understand enough about the Partch System to be able to say something more complete. For now, you will have to listen to the music to get an idea what is going on in the spaces between the notes.
