Heinrich Faber (circa 1570–before 1614) was a German composer and music theorist associated primarily with the late Renaissance and early Baroque periods. His contributions to music are significant within the context of the development of polyphonic vocal music during this transitional era. Faber is best known for his motets and sacred choral works, which showcase intricate counterpoint and rich harmonic textures. Notable compositions include "Missa Brevis" and various motets that reflect the stylistic qualities of the time, blending traditional polyphony with emerging Baroque elements. In addition to his compositions, Faber was also an influential music theorist, and his writings contributed to the understanding of music theory during his time. His works often served educational purposes and were used as models for aspiring composers. While Faber may not be as widely recognized today as some of his contemporaries, his impact on the evolution of choral music and his role in the dissemination of music theory concepts were instrumental in shaping the direction of Western classical music leading into the Baroque period. His works continue to be performed in choral settings, contributing to the legacy of Renaissance music.
