[Planchart 2018]: 'As Wegman demonstrates, [Kyrie] consisted originally of seven sections, which for convenience we can refer to as Kyrie 1–2, Christe 4–5, and Kyrie 7–9. In Br 5557 a number of repeat signs and the indications 1um and 3um in all voices for Kyrie 1 and Christe 4, and 2um in all voices for Kyrie 2 and Christe 5, direct the singers to repeat Kyrie 1 after Kyrie 2, and Christe 4 after Christe 5. In SP B80 the repeat marks and numbers are absent and the same obtains in ModD, which in addition omits all the music for Kyrie 8, thus making all the three divisions of the Kyrie consist of two sections each.
