“Bach - Polonaise in G Minor - BWV Anh. 125” is a short two-page Baroque dance piece in 3/4 time. The music has a serious minor-key character, with a clear right-hand melody, steady left-hand support, short slurs, and small dynamic contrasts. Although it is called a polonaise, this version is compact and student-friendly, focusing more on graceful phrase shape and hand coordination than on large dramatic display.

Measures 1–8 present the opening polonaise idea. The right hand carries the main melody in a clear, lightly articulated shape, while the left hand supports with simple bass notes and harmonic motion. The mezzo forte opening and later forte marking give the first section a confident dance character.

Measures 9–16 continue the dance with a slightly more active phrase. The right hand moves through small stepwise figures and repeated melodic shapes, while the left hand keeps the rhythm grounded underneath. The dynamic contrast between forte and piano helps separate the stronger opening material from the lighter answer.

Measures 17–23 bring back the opening-style material and close the piece. The melody returns to familiar shapes from the beginning, while the left hand supports the final cadence with simple harmonic motion. The ending gives the short dance a clear and balanced close in G minor.

Interesting fact: BWV Anh. 125 is connected with the Notebook for Anna Magdalena Bach, a famous household music collection associated with the Bach family. The “Anh.” label means the piece is in the appendix of the Bach catalog, often used for works connected with Bach but not securely confirmed as his own composition.
