chagall[17] Graphic by Scott Dakota August 2016

Scott Dakota developed a new tuning called “Chagall[17]” and I record a Linnstrument improvisation with pianoteq in the tuning as a demonstration. The tuning is below.

(771/256)^(1/3) generator, ~13/9. Superb scale. Like 17&83 temperament in the 2.7.9.11.13.(23) subgroup. Scott Dakota, July 2016.

phi[8] piano improvisation

follow along score, 8th note reduction

phi[8] piano improvisation is an improvisation in the tuning below. The tuning has two basic interval sizes, ~108 cents and ~175 cents. This would lead you to believe that the tuning is not very harmonious. I found it to be otherwise and also excellent for melodies.

Jake asked for the same improvisation in “minor” mode – the tuning is below.

The tuning was devised by Jake Freivald – phi[8] is a LSLLSLSL mode “major”
