John Donald Robb (1892–1989) was an American composer, musicologist, and educator, primarily known for his contributions to classical music and folk music. He was born in New Mexico and became deeply involved in the cultural landscape of the Southwest, which profoundly influenced his work. Robb's genre spans classical and traditional American folk music, and he is noted for integrating regional musical styles into his compositions. His notable works include the "Symphony No. 1" and a series of choral pieces, as well as numerous folk songs and arrangements that reflect the rich traditions of New Mexico. Robb's most significant impact on music came through his role as a collector and scholar of folk music; he founded the New Mexico Symphony Orchestra and served as a professor at the University of New Mexico, where he helped establish the state's music program. Robb's commitment to preserving and promoting the musical heritage of the Southwest has left a lasting legacy, influencing future generations of composers and musicians interested in regional and folk music. His work continues to be celebrated for its blend of classical techniques with local traditions, enriching the tapestry of American music.
