He was born in Switzerland and later moved to the United States, where he became a significant figure in the academic and performance scenes. Levy is known for his contributions to both chamber music and orchestral works. His notable compositions include "Concerto for Piano and Orchestra," "Symphony No. 1," and various chamber pieces that reflect his intricate understanding of harmony and structure.

As a musicologist, Levy made significant contributions to the understanding of early music and the works of composers such as J.S. Bach, and he published extensively on music theory and analysis. His impact on music lies not only in his compositions but also in his efforts to educate and inspire future generations of musicians.
