A regular bass-and-two-chords pattern runs beneath the upper line.\r\nMeasures 1–8 present the main figure and move it into a higher register. Short sixteenth-note turns grow into a descending run before the phrase pauses on a longer note.\r\nMeasures 9–16 repeat the idea over a changed bass and harmony. Another high-register passage leads into two longer running figures, then a clear melodic resting point.\r\nMeasures 17–24 lift the melody through successive high points and introduce further chromatic notes. Measures 25–28 sweep downward across a wider range before three separated rising notes and a high final note bring the piece to a crisp close.\r\nInteresting fact: The score uses octave signs to move familiar-looking notes into a much higher register, making register itself part of the piece’s changing character.","created_at":"2024-04-17T18:07:21+00:00","first_published_at":null,"published_at":null,"updated_at":"2026-09-22T16:37:49+00:00","match_basis":"filters"}
