The figuration moves into the lower register beneath terse upper chords and develops into denser exchanges (mm. 178–289), before the opening pattern returns (mm. 290–333). Continuous motion then spreads across both hands around a brief cantabile idea (mm. 334–418), and forceful chordal interruptions build a broad climax (mm. 419–502). The opening motion returns once more (mm. 503–571), after which contrary and parallel streams gradually diminish into a sparse, soft coda (mm. 572–621).","created_at":"2026-09-16T06:44:31+00:00","first_published_at":"2026-09-16T06:45:14+00:00","published_at":"2026-09-16T06:45:14+00:00","updated_at":"2026-09-16T06:45:14+00:00","match_basis":"filters"}
