Attribution to Josquin in I-Rv 35–40 (formerly S.Borr.E.II.55–60) and to Mouton in I-Rvat C.S.38. [Anderson 2013] and [Macey 2018] favor the attribution to Mouton on stylistic grounds, specifically for its canonic structure, treatment of the cantus firmus, richness of harmonies, and lenient handling of points of imiation.
V-CVbav-ms-Capp.Sist.38: Composer name in ms ='Johannes mouton' / Title as in ms (index) = 'Confitemini' / [Tenor]: 'Canon Preibis parare via[m] mea[m]'
