Ervin "Erv" McDonald Wilson (11 June 1928, Colonia Pacheco, Mexico — 8 December 2016, Camarillo, California, USA) was an influential Mexican-American music theorist and inventor of microtonal scales and tunings. He originated from a small Mexican village in the mountains of Chihuahua, born and raised in the family of Mormon "mule-and-wagon" pioneers from Utah. Ervin began playing the reed organ at six, learning notation from his mother and soon encountering the limitations of conventional music intervals.
In 1943, Wilsons moved back to the United States. While serving in the US Air Force, Erv discovered musical harmonics and harmonic series from a fellow airman in Japan. In 1948, a University Of Tokyo professor, [url=https://discogs.com/artist/6703324]Hisao Tanabe[/url], also told twenty-year-old Ervin about pentatonic scales in ancient Japanese court music.
After returning from his overseas military service, Wilson briefly studied music theory at Brigham Young University. He dropped out in his sophomore year, though — frustrated with BYU professors who refused to comprehend his concept of "missing" keys in the conventional 12-TET scale — and relocated to California to work as an independent scholar.
Wilson systematically explored all equal octave divisions above the conventional 12-tones, creating original scales of 17, 19, 22, 31 and 41 tones. He invented unique sequences based on complex mathematical theories: recurrence relations, Pascal's triangle, generalized Fibonacci series, binomial coefficients, the Co-Prime grid and other diamonds, Farey Series and Stern-Brocott trees. Erv once described himself as "
natural approximationist of (circa 1927) Novaro School," referring to one of his major influences, Mexican composer and music theorist Augusto Novaro Adame Gómez (1891—1960). Wilson also mentioned Russian-American organist and musicologist Joseph Yasser (1893—1981), who inspired him to think of musical scales as "living" manifestations similar to a crystal or plant.
