The Piano Sonata No. 5 in C minor, Op. 10, No. 1, was composed by Ludwig van Beethoven. It is dedicated to Anna Margarete von Browne, the wife of one of Beethoven's patrons, a Russian diplomat in Vienna. All 3 sonatas of his Opus 10 are dedicated to Countess von Browne.

The first movement of the sonata has a 3/4 meter, the second movement 2/4, and the final movement 2/2. Beethoven's Piano Sonata No. 5 is a first period composition, anticipating more notable C minor works such as the Pathétique Sonata and the Fifth Symphony in its nervous energy.

Form

The sonata is divided into three movements:

1. Allegro molto e con brio in C minor
2. Adagio molto in A flat major
3. Finale: Prestissimo in C minor

First Movement

The first movement, in sonata form, opens energetically with contrasting loud and soft phrases. The theme is highly angular, consisting of rising dotted quaver arpeggios. The exposition lasts from mm. 1-105. The primary theme, a modified sentence structure, lasts from mm. 1-30. The transition, which is separately thematized and provides a quiet contrast, is in two parts and lasts from mm. 31-55. The secondary theme, which is accompanied by an Alberti bass, lasts from mm. 56-75 and ends with the essential expositional closure. The closing section, which is in two parts, quotes the secondary theme and liquefies the primary theme. The development (after Darcy/Hepokoski's Sonata Theory) is half-rotational and divides into pre-core and core sections (after William Caplin); it lasts from mm. 106-168. The retransition, mm. 158-167, leads into the recapitulation. The recapitulation lasts from mm. 168-284, 11 measures longer than the exposition. The exposition’s transition is altered harmonically in the recapitulation. Initially, the secondary theme is stated in F major (predominant), a “false start,” before being stated in tonic C minor. The secondary theme is also expanded from the exposition. The essential structural closure is in m. 253.

Second Movement

The second movement is a lyrical Adagio with many embellishments. It is in A-B-A-B or "sonatina" form (there is no development section, only a single bar of a rolled V7 chord leading back to the tonic key); an apparent third appearance of the main theme turns into a coda, which slowly fades to a final perfect cadence.

Third Movement

The third movement is a highly nervous piece in sonata form, making heavy use of a figure of five eighth notes. The short development section contains an unmistakable foreshadow of the theme from Beethoven's Fifth Symphony. The coda slows the tempo down, leading to a final outburst which fades to a quiet but agitated Picardy third.
