Scale of the Day: A Ionian mapped to the Triative

<span class=

The A Ionian mapped to the Triative Scale. The triative is the frequency ratio of 3/1 - an interval roughly the size of an octave plus a perfect fifth at 1901.96 cents wide. Here the standard, equal tempered "A major" scale is stretched to fill the larger interval space and the ear is surprisingly accepting of the 3/1 as a harmonic equivalent. Experimenting with the disorienting effect of playing familiar, diatonic melodies re-mapped to this harmonic terrain appeals to my subversive sensibilities.
Blogging from the East Coast resumes with this post. It's good to be home.
