Sonata in G, C. 34

Cimarosa is best remembered as a Neapolitan opera composer (Il matrimonio segreto, 1792), but his thirty-odd one-movement keyboard sonatas — small, witty, perfectly formed — circulated widely in the late eighteenth century and remain a staple of intermediate teaching. Sonata in G, C. 34, is one of the brightest: a single Allegro in clear binary form, songlike rather than virtuosic.

Technically the piece tests cantabile right-hand playing in a Classical idiom. The melody is mostly stepwise with tasteful ornaments at cadences; the left hand provides Alberti-style broken triads and a few walking-bass passages. Articulation matters — the score asks for a mix of legato phrases and lightly detached cadence figures, and the contrast is what gives the piece its operatic lift.

Two pitfalls. First, students play it too straight — Cimarosa's sonatas live on a sense of vocal phrasing, breathing at line-ends rather than steamrolling through. Second, the Alberti bass becomes mechanical; it needs a gentle shape that follows the melodic arch, not a flat carpet of semiquavers.

Listening: PD recordings of Cimarosa keyboard sonatas are widely available (Musopen, IMSLP audio); historical-instrument recordings tend to give the clearer articulation reference for a Grade 4 student.
