Johann Tobias Krebs (1690–1762) was a German composer and organist, primarily associated with the Baroque genre. He was born in the town of Weimar and became known for his contributions to sacred music, particularly in the context of Lutheran church services. Krebs was a student of the renowned composer J.S. Bach, and he held various positions, including organist at the St. Thomas Church in Leipzig. Krebs is best known for his chorale preludes and organ works, which exhibit intricate counterpoint and rich harmonic language typical of the Baroque style. His notable works include a collection of organ compositions, "Sechs Präludien und Fugen" and numerous chorale preludes, which showcase his skill in writing for the organ and his deep understanding of liturgical music. Krebs' impact on music is significant in that he represents the transitional phase from late Baroque practices to the early Classical style. His works are often studied for their technical mastery and are valued in the repertoire for organists. Although not as widely recognized as Bach, Krebs' music contributes to the understanding of the evolution of German organ music during the 18th century.
