A demonstration of 5-tone equal temperament (5edo, 5ET, or 5TET), played on an electric keyboard, using MIDI and the Logic program, by Ryan Curtis Jackson on February 20, 2019. Jackson chose to keep F-sharp as his reference pitch so he could use the black keys on the keyboard.
This tuning divides the 1200-cent octave into five equal parts, producing a pentatonic scale in which each step measures exactly 240 cents.
The intervals are as follows (all values in cents):
========
0 - unison
240 - "large second" (8.8 cents higher than the septimal second, 8/7)
480 - "narrow fourth"
720 - "wide fifth"
960 - "low seventh" (8.8 cents lower than the septimal seventh, 7/4)
1200 - octave
Not just being a theoretical abstraction, this tuning is used in Indonesia (the slendro tuning used in gamelan and other musics comes close to 5-tone equal temperament, although it is distinctly/intentionally slightly unequal) as well as in Central Africa (among the Pygmies and some Bantu-speaking ethnic groups).
