Movement 1: Allegro maestoso e con sentimento
Movement 2: Adagio sostenuto e patetico
Movement 3: Allegro vivace
The first sonata of Op 50, in A major, has an opening movement with something of the transparent texture and lyrical melody that Clementi seemed to associate with this key, as in his Sonata Op 33 No 1, and even as far back as Op 2 No 4. For a slow movement Clementi writes a rather leisurely two-voice canon flanked by two statements of a lugubrious, harmonically potent Adagio sostenuto e patetico that anticipates the subject of the canon in its middle section. The finale, a spritely Allegro vivace, mixes traditional harmonies with the distinctly nineteenth-century sound of the expanded upper range of the piano.
