Variants

The catalogue of variants lists differences between the sources and the edition by Source, Piece, Voice, Location (verse [if applicable], measure number, and note number), Reading, Type, and Subtype. If verse is not specified, the variant applies to the first section of introits and alleluias.

Differences among the sources are reported as variants, with the following exceptions:

• Differences in coloration are not reported.
• Differences in chant incipits are reported only for the Choralis II print. Incipits in other sources often correspond to local versions of chants and differ in minor ways from those in the edition.
• Differences in text underlay are reported only if the apparently intended underlay differs from that in the edition. Phrases without text are assumed to call for either a repeat or an extension of the preceding text. The Underlay subtype "No text" is specified only when the implied text differs from that in the edition.
• Differences in text repetitions, which are often ambiguous in the sources, are reported only for the Choralis II print. Text repetitions called for in the print that are omitted in the edition are reported as variants. Text repetitions that are added editorially are in italics.

Errors corrected in-house are not included. They are listed under in-house corrections.

Variants are classified in the following categories and subcategories:

• Accidental
  • Additional: explicit accidental in the source that is not in the edition
  • Lacking: explicit accidental in the edition lacking in the source

The editors have attempted to distinguish between variants and errors in all applicable categories. There are cases where this distinction is not clear, however, and the assigned category is a matter of judgment.
