RE Roman Fruth

Christopher: According the notes on the back of the jewel box, the tuning is by 31-tet fourths from C to Ab and by 31-tet fifths from C to Cx. and Roman's harmony is based 4:5:6:7 tetrads and occasional 11/8s and 13/8s in tempered approximation. The jewel box notes say only "prepared piano." Needless to say, I'd like to ask some questions as well as thank him for the disc.

Thank you for the information ; I've set the scale up in FTS for inspection – curiously enough, I was toying with a 19-tone Pythagorean chain awhile back ; it will be interesting to compare these ( this being a 31TET 19 chain ), along with 19TET.
Fell free to share any further information! – and thank you again.
