George Secor
George Secor (November 8, 1943 – March 2, 2020[1]) was an American musician, composer and music-theorist from Chicago.
As an inventor, Secor and Hermann Pedtke's Motorola Scalatron (1974) is an example of a Bosanquet generalized keyboard featuring a multicolored arrangement of 240 tunable oval keys, about which Secor said: "There is not much point in using this alternative keyboard for systems below 31 tones in the octave.
"[3] However, "even if it were completely impractical musically, it would make a wonderful prop for a futuristic movie.
"[3] Though its synthesizer capacities may not reach performance level, according to Easley Blackwood, "It has rock-steady tuning capabilities; you can always count on it to be right.
George was also an accomplished musician and proponent of the Moschino Free-Bass Accordion system.
A YouTube channel with some of George's performances on Moschino Accordions illustrates his abilities on their unique keyboard, which allows for chromatic runs and open chords with the left-hand buttons, a Free-bass system, rather than the more common Stradella bass system, which has fewer bass notes, plus preset chord buttons.
George was interviewed in 2018 about the origin and organization of the Moschino accordion system here.
Secor devised it to allow a close approximation, generated from a single interval, to Harry Partch's 43 tone just intonation scale.
[4] For tuning purposes, a secor of seven steps of 72 equal temperament is often used.
is tempered out, and two secors give an 8:7 interval, a septimal whole tone.
In miracle, a minor third plus a septimal whole tone is also equated with the 11th harmonic.
For tuning purposes, a secor of seven steps of 72 equal temperament can be used.
While this also tempers out 4375:4374 (the ragisma), doing this is not regarded as a part of the definition of miracle temperament.
The twenty-one note Blackjack scale is derived from twenty successive secors and has been used by several composers, including New York composer Joseph Pehrson.
