“Bach - Invention No. 1 - BWV 772” is a two-part contrapuntal keyboard piece built from one small musical idea that is passed back and forth between the hands. The texture stays clear and lean throughout the piece, but it is constantly active. Instead of a melody with accompaniment, both hands take part in the musical conversation, using imitation, sequences, running sixteenth notes, and small rhythmic answers.
Measures 1–6 introduce the main idea of the invention. The right hand begins alone with the short rising figure, and the left hand answers with the same idea shortly after. From there, the music starts moving in two independent lines, with the subject and running patterns traded between the hands.
Measures 7–14 develop the opening material through sequences and imitation. The same small figures are repeated at different pitch levels, and the hands continue answering each other. The texture stays light, but the motion becomes more continuous as the lines overlap.
Measures 15–21 move into the main middle section of the piece. The writing becomes more active, with the sixteenth-note patterns moving quickly between the hands and the harmony shifting through new areas. The music grows through crescendos and stronger dynamic markings, giving this section more energy than the opening.
Measures 22–end bring the invention back toward a clear final cadence. The two voices continue trading the same motivic material, but the harmony begins to settle. The final measures use repeated running figures and a stronger closing motion, bringing the piece to a clean and confident ending.
Interesting fact: Bach’s Invention No. 1 has been recorded by many famous pianists, including Glenn Gould. Gould’s recording of Bach’s Two-Part and Three-Part Inventions became one of the best-known modern piano recordings of the set, showing how these short teaching pieces can still sound sharp, brilliant, and highly personal in performance.
