The LilyPond source is read by a strict reader for the subset of LilyPond used by the edition (relative pitches, durations, bar checks, manual beams, a volta repeat with two alternative endings, manual line breaks, which are read and not encoded, lyrics with hyphens, extenders and skips). Accidentals are written where LilyPond's default accidental rule prints them; every altered note also carries its sounding accidental (@accid.ges). Lyrics are attached to notes with LilyPond's \lyricsto rules. Only the first, untransposed \book of the score template is converted. Any construct outside the subset stops the conversion. No music was entered or corrected by hand.
All notes, rests and syllables come from the source edition's LilyPond file at the pinned commit, converted mechanically. Nothing was transcribed from the manuscript for this encoding.
Pitch, onset and duration of every note and the placement of every syllable were checked automatically against the edition's own MIDI file (checks/midi-compare.json).
Accidentals: written accidentals are encoded where LilyPond's default accidental rule prints them in the edition; sounding alterations are given in @accid.ges on every other altered note.
Each voice carries its own text (cantus 'Iacob scalam', tenor 'Pax eterna', bassus 'Terribilis est locus iste'), one lyric line per voice, as in the edition. Lyrics, punctuation and spelling are copied from the edition.
The edition writes the whole piece as one volta repeat with two alternative endings. The endings are encoded as MEI ending elements (n='1' and n='2', labelled '1.' and '2.'), the first closing with a repeat bar line, as LilyPond prints them; LilyPond prints no start repeat sign at the beginning of the piece, and none is encoded. The edition's MIDI file plays the music as written (the repeated music once, then both endings), and the MEI is compared with it in that order.
Beams are encoded where the edition beams explicitly (the edition switches automatic beaming off). Layout instructions of the edition (page size, staff size, system spacing, line breaks) and its ambitus signs at the start of each staff are not encoded.
Converted mechanically from the LilyPond source of Monique Rio's edition (St Cecilia Press, commit dcbcfbe) with tools/stcpress.py 1.3.0. No note, rest or syllable was added, removed or corrected by hand.
