He is often associated with the nationalist movement in music, which sought to incorporate indigenous themes and elements into contemporary compositions. Chávez's work is characterized by its rhythmic complexity and use of Mexican folk melodies. Notable works include "Sinfonía India" (1936), which fuses orchestral music with indigenous influences, and "Piano Concerto" (1938), showcasing his innovative use of harmony and rhythm. He also composed ballets such as "La mulata de Córdoba" and various chamber works that reflect his deep engagement with Mexican culture. Chávez was instrumental in establishing the Mexican School of Music and served as the director of the Mexican Symphony Orchestra. His influence extended beyond composition; he was a mentor to younger musicians and played a crucial role in promoting music education in Mexico. His efforts helped to elevate Mexican music on the international stage, making him a key figure in the 20th-century classical music landscape.
