The second movement of Beethoven’s Sonata No. 6 is an Allegretto in F minor and three-quarter time. Its restrained opening, connected phrases, and dark chord colors provide a contrast to the lively outer movements. A broad middle section changes the key and texture before the opening character returns in a written-out, altered form.

The opening begins softly, with an upward-moving line shared across the keyboard and short answering chords. The first phrase is repeated. Around measures 10–20, the right hand extends the melody while the left hand supplies spaced chords and quieter supporting notes. Slurs join the phrases, while rests leave small gaps between the musical statements.

Around measures 25–35, the texture becomes more insistent. Repeated chord attacks, accents, and a short ornament lead toward the end of the opening section, which also carries a repeat sign. The movement’s quiet beginning therefore develops into a firmer statement before the contrast arrives.

The middle section changes to a five-flat key signature. Around measures 40–55, repeated chords support longer notes, with ties carrying parts of the harmony across the bar lines. The music gradually moves through different registers and dynamics. Around measures 70–100, sustained upper notes and connected bass motion alternate with more active right-hand figures, giving this central span a broader shape.

The return begins near measure 125, after the original four-flat signature is restored. Familiar melodic shapes reappear with changes in accompaniment and spacing. The last page includes more flowing bass figures, short chordal replies, and a gradual settling of the motion. The closing bars become quiet and sustained, ending with a held chord and fermata.

Interesting fact: This sonata’s central contrast is marked Allegretto, rather than a conventional slow Adagio. Its darker key and sustained writing create the contrast while the three-beat dance pulse remains present.
