This trio sonata, originally for organ, influenced Mozart who adapted its movements for string trio. Its three contrasting movements showcase Bach's contrapuntal mastery while maintaining emotional depth characteristic of his late Baroque style.
One of six trio sonatas Bach composed pedagogically for his son Wilhelm Friedemann,
combining intricate counterpoint with virtuosic organ technique. The trio sonata format
(two manuals and pedal) creates a dialogue between voices characteristic of Baroque
chamber music.
