**Erv Wilson** (June 11, 1928 – Present) was a prominent Mexican-American music theorist, celebrated for his mentorship of composers and instrument builders. As a dual citizen, Wilson’s contributions to the realm of microtonal music and just intonation have left a lasting impact, particularly in the areas of scale, keyboard, and notation design.

A Manifestor in Human Design, Wilson possessed a unique ability to initiate and innovate within the music community. His Emotional Inner Authority guided his creative processes, allowing him to navigate the complexities of musical expression with depth and sensitivity. His strategy of informing others about his ideas and discoveries made him a respected figure among his peers, as he shared his insights into the architecture of musical scales.

Wilson’s influential developments include Moments of Symmetry, Combination Product Sets, Golden Horograms, and scales based on recurrence relations, notably the scales of “Mt. Meru.” He was instrumental in mapping these scales to generalized keyboards, making microtonal music more accessible to both composers and listeners. His work was inspired by the teachings of notable figures such as Augusto Novaro and Joseph Yasser.

In addition to his theoretical contributions, Wilson was an accomplished builder of musical instruments, exploring the possibilities of 31 and 41 equal divisions of the octave. He was a strong supporter of Harry Partch, collaborating on the construction of the Quadrangularis Reversum and providing essential diagrams for Partch’s seminal book, *Genesis of a Music*.

Wilson’s Human Design profile as a 4/6 reflects his role as a teacher and role model, emphasizing his commitment to guiding others in their musical journeys. His Incarnation Cross, the Right Angle Cross of Rulership (45/26 | 22/47), highlights his leadership qualities and his ability to influence the music community profoundly.

“I sculpt in the architecture of the scale. Other people come along and animate it,” Wilson remarked, encapsulating his vision of music as a collaborative and evolving art form. His legacy continues to inspire those interested in the intricate world of microtonal music and just intonation.
