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 triplet, editorial accidentals marked with the edition's \ficta command, an upbeat, spacer rests with duration multipliers, volta repeats, music and lyric variables, bar lines, lyrics with hyphens, extenders, skips, stanza labels and quoted syllables, and a layout block that hides empty staves and removes the ambitus). As in LilyPond, bar lines and repeat signs apply to the whole score, also where they fall inside a measure. 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. Accidentals the edition marks with its \ficta command (printed above the note) are encoded as editorial accidentals (accid with func='edit', place='above').
The edition opens with the burden for altus and tenor, then writes stanzas and burden twice as volta repeats: the altus carries stanzas 1-3 under the first repeat and 4-6 under the second (lyric lines 1 to 3, with their stanza numbers encoded as verse labels); the tenor carries text only in the burden at the end of each repeat, and the bassus sings only there. Lyrics, punctuation and spelling are copied from the edition, including 'and the', which the edition sets to one note as one syllable.
Both repeats begin and end on the third beat of a measure, and the double bar line before the burden in each repeat also falls on a third beat; LilyPond prints the repeat signs and the bar line at those points. 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, the number LilyPond counts. The edition's MIDI file plays each repeat once, and the MEI is compared with it without the repeats.
The bassus is written with rests in the opening burden and with spacer rests (LilyPond 's2. * 18') during the stanzas, and the edition's layout block hides empty staves in every system, the first included (\RemoveEmptyStaves with remove-first), so the bassus staff is printed only where it sings. The spacer rests are encoded as MEI space elements, one or more per measure; the setting is recorded as scoreDef optimize='true'.
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) are not encoded; the edition removes the ambitus signs its layout file would add, and none are 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.
