A low, rocking bass supports a melody embedded in warm upper harmonies.\r\nAfter a one-measure bass introduction, measures 2–9 present the main chordal tune. Measures 10–17 repeat it while moving the accompaniment an octave higher.\r\nMeasures 18–33 shift the harmonic color and introduce a more rising upper contour. This material also appears over two bass registers. Measures 34–41 return to the original theme and the deep opening accompaniment.\r\nInteresting fact: Register provides a major source of contrast: entire phrases keep their upper harmonies while the repeating bass pattern moves up or down an octave.","created_at":"2024-04-17T18:11:48+00:00","first_published_at":null,"published_at":null,"updated_at":"2026-09-22T17:54:49+00:00","match_basis":"filters"}],"latest_catalog_version":23456,"source_lag_revisions":0}
