A. Staves 01-04 and 06-09: first layer. Two voices of a setting of 'Magnificat anima mea dominum', the canticle daily at Vespers. Notation: black full. Copied perhaps c.1450-70. Original composition for three or four or (less likely) five voices, for festal use; as usual, an alternatim setting, with polyphonic music for verses 2, 4, 6, 8, 10, and the second verse of the doxology, leaving the remainder to be sung in plainsong.
B. Staves 05, 11: second layer. Notation (black void, with black full coloration) and text added c.1500-20 on staves drawn previously but thitherto left blank. Stave 05. Opening lines of second stanza of 'Iste confessor domini sacratus', hymn at first Vespers on any feast of a sanctified Confessor bishop.
Stave 11. Cue to opening line of first stanza of 'Exultet celum laudibus', hymn at Lauds on any feast of an Apostle who did not have a special Office of his own.
Hymns set in polyphony were sung alternatim, odd-numbered stanzas in plainsong, even-numbered stanzas in polyphony. For 'Iste confessor' stave 05 gives the correct second-stanza text ('Qui pius prudens ...'). Stave 11 gives just a cue, identifying the hymn rather than giving the second-stanza opening.
