“Bach - Polonaise - BWV Anh. 119” is a short Baroque-style keyboard piece in 3/4 with a light Allegretto character. The music is built around small slurred figures, simple two-hand motion, repeated sections, and quick dynamic contrasts between f, p, and mf. Even though the piece is short, it has a clear dance shape and a more active second half.

Measures 1–4 present the first repeated section. The right hand carries the opening melody with short slurs and small stepwise motion, while the left hand supports with simple bass notes and moving tones underneath. The quick f-p marking gives the opening a small echo effect right away.

Measures 5–12 begin the second repeated section. The melody becomes more active, with quicker eighth-note motion and longer slurred shapes between the hands. The left hand continues to support the dance rhythm with simple bass movement instead of thick chords.

Measures 13–16 close the piece with the most active writing on the page. The right hand moves through a quicker running figure while the left hand gives steady support below. The short crescendo near the end helps lead into the final cadence and gives the piece a clean, confident finish.

Interesting fact: BWV Anh. 119 comes from the 1725 Notebook for Anna Magdalena Bach, but it is one of the pieces with doubtful attribution to J. S. Bach. That makes it similar to several other famous beginner Baroque pieces: it has long been taught under Bach’s name, but the exact composer is not fully certain. Notebook for Anna Magdalena Bach
