Piano Sonata No. 11 in B-flat major — Adagio

Piano Sonata No. 11 in B-flat major — Adagio by Ludwig van Beethoven, catalogued as Op. 22, is a work for solo piano in B-flat major. Composed during the Classical era, it forms part of the composer's enduring contribution to the keyboard repertoire and is freely available in the public domain through archives such as IMSLP.

Ludwig van Beethoven's thirty-two piano sonatas form the most important single body of work in the keyboard repertoire — what Hans von Bülow called the New Testament of the piano. Across four decades they trace the journey from late-Classical wit to the visionary, fragmented spiritualism of the late style.

The work is suited to advanced-level pianists. As with all repertoire from this period, study editions vary; the public-domain engravings linked here are based on the most widely-circulated nineteenth- and early-twentieth-century editions and are sufficient for serious study, recital preparation, and recording.

Key character — B-flat major

Stately, reflective, often nocturnal. Schubert's last sonata is a luminous example.

The Classical Era

The Classical era refined keyboard music around the new fortepiano, favoring balanced phrases, clear textures, and sonata-form drama. Mozart, Haydn, and the early Beethoven shaped a vocabulary of grace and rhetorical wit that still anchors the modern repertoire.

About the Sonata form

The sonata is the central architectural form of Classical and Romantic keyboard music: typically three or four contrasting movements built around the dramatic dialogue of sonata-allegro form. From C. P. E. Bach's first essays through Beethoven's 32, Schubert's last great cycle, and the Romantic single-movement experiments of Liszt and Scriabin, the sonata absorbs every major shift in keyboard thinking.
