Its three-beat meter gives the opening an easy swing, but the movement soon reveals a much wider range of characters. Singing phrases, firm chords, quick ornamental gestures, and sudden changes of color follow one another with remarkable variety. This is an advanced movement in which clear phrasing and alert changes of touch matter as much as fluent fingers.\r\nThe opening section introduces several contrasting kinds of writing. The first melody needs a smooth line above the accompaniment, while later phrases bring more pointed rhythms and stronger chordal replies. Running figures and grace notes add brilliance without replacing the underlying melody. In quieter passages, the hands sometimes have different jobs: one sustains or shapes a line while the other supplies short, detached notes. Listen for these changes of role so that the texture remains conversational rather than uniformly accented.\r\nThe exposition moves toward a closing passage with trills and busy broken chords in the left hand. Its repeat gives the listener another opportunity to hear the contrasts clearly. The middle section develops earlier gestures through changing harmonies and registers. Repeated chord figures and alternating loud and soft responses create tension before the opening theme returns. In the recapitulation, familiar ideas are reshaped to settle in the home key, and the final closing passage combines ornamented melody with an energetic accompaniment. The score also repeats this second large section.\r\nPractice the left-hand patterns with a relaxed, even motion, then add the melody without allowing the accompaniment to grow heavier. Where triplet figures occur beneath a differently divided upper line, establish the beat before increasing speed. Double notes should sound together, and a short slur should have a clear destination and release. Treat rests as part of the phrase, especially in the passages that alternate crisp chords with brief silences.\r\nOne striking feature visible in this score is the frequent change from a forceful attack to an immediate quiet response. These contrasts can occur within a very small space, so a single overall dynamic is not enough. Prepare the change in touch ahead of time and keep the pulse steady through it. A successful performance preserves the opening’s poise while making the more dramatic episodes vivid and distinct.\r\nHow to earn points for this piece:Download or purchase the sheet music.Practice the piece carefully.
