The piece

The four Impromptus D. 935 date from December 1827 but were only published in 1839, by Diabelli, who dedicated them to Franz Liszt. Robert Schumann, reviewing them, saw the first, second and fourth as the movements of a sonata. This one, an Allegretto in three, moves in full chords like a calm minuet; its trio, in D-flat major, unfolds in continuous triplets, and then the Allegretto returns in full.

The chords of the first part ask for an even touch from every finger: let the top note sing and keep the others in the background. In the trio the right hand runs in triplet eighths while the left holds the bass: keep the flow steady, with no bump at each change of position, and let the bass ring under the triplets.
