George Secor

George Secor (November 8, 1943 – March 2, 2020) was an American musician, composer and music-theorist from Chicago. He was the discoverer of miracle temperament and eponym of the secor.

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." However, "even if it were completely impractical musically, it would make a wonderful prop for a futuristic movie." 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 demonstrating the micro-tonal keyboard instrument can be seen in this demonstration video.

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.

The system is explained in a video Additionally, a written discussion of the organization of the system, including Georges own explanations and diagrams is included on accordionists.info.

In music, a secor is the interval of 116.7 cents ( ( 18 / 5 ) 1 / 19 ) Play named after George Secor. Secor devised it to allow a close approximation, generated from a single interval, to Harry Partch's 43 tone just intonation scale. All 11-limit consonances are approximated to within 3.32 cents.

It is approximated in 31 Play, 41 Play, and 72 equal temperament Play. For tuning purposes, a secor of seven steps of 72 equal temperament is often used.
