Sincerity in C major, Allegro moderato: an even, flowing line of eighth notes in the right hand over held chords (bars 1-8), then in the left hand under held thirds in the right (bars 9-12); in bar 13 the right hand holds a two-note melody above its own eighths. A smooth legato and a singing top line.
How to practise it
In bars 1-8 the left hand only holds chords, so give your attention to the right hand's eighths. Keep them even and smooth, p and dolce.
Bars 9-12 are the hard spot: in bars 9 and 11 both hands play eighths together, then in bars 10 and 12 the right hand holds a third while the left keeps going. Loop them at 100 BPM.
In bar 13 your right hand holds G and then F♯ on top while it plays its own eighths below. Let the held notes ring and keep the eighths soft.
