This YouTube Short presents a 60-second excerpt from Johann Sebastian Bach’s Invention No. 4 in D Minor, BWV 775. This piece belongs to the collection of fifteen two-part inventions that Bach composed as teaching material for his students, including his son Wilhelm Friedemann Bach. Although intended for pedagogical purposes, these inventions are among the most elegant examples of Baroque contrapuntal writing. The inventions explore two-voice counterpoint with exceptional clarity. Invention No. 4 is a compact yet highly expressive piece, characterized by rhythmic vitality, imitation between the hands, and a sense of forward momentum that unfolds naturally from the opening motive. Despite its brevity, the invention contains a complete musical argument, offering a glimpse into Bach’s ability to craft structurally coherent, expressive music with limited means. This short video presents the music entirely without commentary or spoken explanation, allowing the listener to focus exclusively on the clarity of the lines, the balance of the two voices, and the characteristic Baroque articulation. Even in a brief excerpt, the listener can hear the interplay between subject and countersubject, and the way Bach shapes the tension and release through sequences, harmonic progressions, and motivic development. Bach’s inventions continue to play a central role in keyboard training, not only for their technical demands but also for their pedagogical insight. They encourage independence of the hands, control of touch and phrasing, and a deeper understanding of linear musical thinking. For many pianists and harpsichordists, they are the first substantial encounter with real polyphonic writing. In Invention No. 4, Bach uses a distinctive rhythmic profile that propels the music forward from the opening bars. The piece unfolds in a clear trajectory, moving through closely related harmonic regions before returning to the home key. The writing shows Bach’s precision and concision: ideas are introduced, developed, varied, and concluded with a sense of inevitability that characterizes his best keyboard works. This short recording offers a moment of focus and calm, suitable for listeners who appreciate Baroque counterpoint, early keyboard repertoire, or brief encounters with classical music. It can serve as an introduction to the complete set of inventions, which remains a foundational part of the keyboard canon. Whether you are a performer, a student, or a listener who enjoys the clarity and symmetry of Bach’s music, this 60-second excerpt provides a concentrated glimpse into the craft of one of history’s greatest composers.
