!This set of notes is sufficient to play all 8 species of the Ellis Trichordals
!(ma.ma.ma. through mi.mi.mi.) of the 3 types, D->T, M->T, and D->M with 1/1 asa
!common tonic. By modal rotation, all 56 modes of each type are playable. The
!D->M contain 2 each of 6,7,and 8 tone scales; the other type only 7 tone scale.
!For further symmetry, add 25/18 to make 14 tones.
