About the piece
Invention No. 4 in D minor is one of the Fifteen Two-Part Inventions composed by Johann Sebastian Bach around 1720. Originally written for keyboard instruction, these pieces serve as essential studies in counterpoint and independent finger dexterity.
The piece is famous for its lively, energetic theme that bounces between the left and right hands. Mastering this invention is a rite of passage for pianists as it trains the brain to listen to two distinct musical voices simultaneously.
Which level should you choose?
- Right hand only: focus entirely on the primary subject and the melodic lines in the upper voice, perfect for internalizing the rhythmic patterns.
- Both hands: the complete two-part counterpoint where both hands engage in a musical dialogue. Recommended once you have mastered the independence of each individual part.
Fingering and hand position
Because this piece features constant movement, maintain a flexible wrist and light touch. Keep your hands in a relaxed, curved position to allow for quick transitions between positions.
Practice playing with a steady, non-legato touch to highlight the clarity of the lines. Focus on keeping your fingers close to the keys to avoid unnecessary tension when navigating the more agile, rapid sections of the invention.
Practice tips
- Listen to the full version multiple times to understand how the hands interact.
- Slow down the speed significantly in Rhythm mode until every note is precise.
- Isolate the most difficult measures and repeat them slowly before playing the full phrase.
- Watch the falling notes carefully to identify where the thematic subject reappears in each hand.
Learn it step by step
Start by learning the melody in the right hand alone until you can play it comfortably from memory. Once that is secure, practice the left hand separately to grasp its specific role in the counterpoint.
Only combine the hands after you have achieved complete confidence with each part individually. Begin at a very slow tempo, gradually increasing the speed only when your accuracy is perfect.

Who composed Invention No. 4?
Johann Sebastian Bach, as part of his collection of Fifteen Two-Part Inventions, intended as pedagogical works for his students.
How long does it take to learn this piece?
Due to its contrapuntal nature, it typically takes several weeks of consistent, dedicated practice to perform the full piece fluently at tempo.
