Bach’s Prelude No. 3, BWV 926 is a short Baroque keyboard prelude in D minor, written in 3/4 time. The music has a quick, flowing character, built mostly from broken-chord sixteenth-note patterns, short ornaments, steady bass notes, and two-hand imitation. Instead of a long singing melody, the piece moves through repeated arpeggio shapes and harmonic sequences, giving students practice with even fingerwork, clear hand coordination, and Baroque-style phrase direction.

Measures 1–4 introduce the main pattern. The right hand plays steady broken-chord figures while the left hand gives simple bass support underneath. The texture is light and continuous, and the small ornaments at the beginning of the phrases add a Baroque decorative sound.

Measures 5–8 continue the same flowing sixteenth-note motion, but the harmony begins to move more actively. The right hand shifts through new broken patterns, and the left hand begins to add more motion instead of only holding simple bass notes. This gives the music a stronger sense of forward movement.

Measures 9–16 bring more imitation and contrast between the hands. The right hand plays descending figures and short melodic shapes, while the left hand answers with similar motion below. Several accidentals appear in this section, creating a more searching harmonic sound before the music continues into the next passage.

Measures 17–24 return to a more regular broken-chord texture. The right hand moves through steady patterns while the left hand supports with bass notes and simple moving tones. This section feels more settled than the previous one, but the harmony still keeps moving forward.

Measures 25–36 continue the running sixteenth-note style with more repeated arpeggio shapes and small harmonic changes. The hands stay coordinated in a clear two-voice texture, with the right hand usually carrying the faster motion and the left hand outlining the bass.

Measures 37–42 lead into the most active part of the prelude. The texture becomes more dramatic, with quicker broken figures and longer running passages that move across the keyboard. This section feels like a small flourish before the final cadence.

Measures 43–48 form the closing passage. The music returns to a clearer two-hand texture, with short melodic figures, a trill, and a final strong chord. The fermata at the end gives the piece a clear and finished Baroque-style ending.

Interesting fact: BWV 926 comes from the Klavierbüchlein für Wilhelm Friedemann Bach, a notebook Bach began for his son in 1720. The collection was used for keyboard study and included pieces that helped develop technique, musical understanding, and creativity.
