This Sonata in F sharp minor first appeared in a manuscript of other Scarlatti sonatas and pieces in Venice in 1742. However, virtually all the music in it is believed to have been written during or before 1719, the year the composer departed Italy for Portugal. This particular Sonata is short, even for Scarlatti — typically running about one-and-a-half minutes — and bears stylistic characteristics found in the toccata style of his father, Alessandro Scarlatti. The Sonata, K. 67, is thus almost certainly a very early work, predating the “before 1742” description in the headnote by as many as three decades.
Marked Allegro, the work brims with energy that would normally suggest a Presto marking. Not surprisingly, the piece requires a virtuosic technique to properly execute its difficult demands. The thematic material springs from the opening chord — a chord that spawns rich motivic activity that scampers breathlessly up and down the keyboard. In the latter half of this mini-Sonata there is some limited development of materials, but the kinetic drive of the music remains constant throughout, the busy manner never pausing to catch its breath or to settle into a calmer or sweeter emotional state.
