Why did Dieterich Buxtehude influence Bach?

Dieterich Buxtehude significantly influenced Johann Sebastian Bach through his innovative approach to church music, particularly in the realm of organ composition and liturgical practices. Buxtehude's use of complex harmonies, intricate counterpoint, and expressive melodies inspired Bach's own compositions, especially his organ works and cantatas.

This encounter emphasized the importance of improvisation and the integration of various musical forms, leaving a lasting impact on Bach's oeuvre.
