Written pitches, independent source underlay and complete performed extent retained. Layout-only directives remain in the source record. Tempos and singer registers are curated starting points; written pitches are never fitted to comfort ranges. Octave-treble inner clefs and part names corrected against the publisher PDF without transposing pitches.
Digital edition credited in the retained LilyPond source. The hosting site expressly provides the source files for modification; no named blanket redistribution licence is stated there or in this file.
