Handwritten annotations in the Regensburg copy of Choralis II

  • B, Sequence 24 (verse 8), fol. PP1v, staff 3 (beginning): word “Nota” added, perhaps to call attention to the fact that the tenor is derived canonically from the bass

• Numbers added showing semibreve counts above notes in proportional notation or complex ligatures

• B, Sequence 1 (verse 8), fol. AA3r, staff 3: word “dupla” above beginning of staff, then “2" above breve following ₵, then diagonal ovals (apparently meaning “1") above all of the following notes before the final long
• B, Alleluia 25, fol. PP4r, staff 1: number “1" over each note in duple and quadruple proportion
