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, ties, an upbeat, time changes, melisma marks, bar lines, lyrics with hyphens, extenders, skips and stanza labels, and a layout block that hides empty staves). As in LilyPond, time signatures and bar lines apply to the whole score, also where they fall inside a measure, and every staff runs to the end of the score. 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.
The burden ('Ther is no rose of swych vertu / As is the rose that bare Jhesu') is sung by all three voices and carries its text under each of them; the verse that follows is set for cantus and tenor, with the five stanzas under the cantus as lyric lines 1 to 5 and their stanza numbers encoded as verse labels. Lyrics, punctuation and spelling are copied from the edition.
The piece begins with a quarter-note upbeat, so the double bar line after the burden and the final bar line fall inside a measure, where LilyPond prints them. MEI measures end at bar lines, so each of these measures is encoded as two measures with metcon='false' that carry the same bar number, which is the number LilyPond counts; the last measure of the piece is incomplete (metcon='false').
The altus sings only the burden. LilyPond keeps its staff to the end of the score with nothing in it and, because the edition's layout block sets \RemoveEmptyStaves, does not print it in the systems where it is empty. The MEI fills the altus with measure-long space (mSpace) in every measure after the burden and records the setting as scoreDef optimize='true'.
The edition writes the changes to 9/4 and back to 6/4 in the cantus and the tenor; they are encoded once for the score.
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 1.4.0. No note, rest or syllable was added, removed or corrected by hand.
