note: this lauda is a cc. for several other laude with the same incipit, and is transmitted as a lauda with a modo proprio. The cc. incipit may refer to this modo proprio, perhaps a secular song upon which Razzi drew for his 3-part setting of this lauda text. The cantus of Razzi’s version is identical to the 2nd superius of Francesco Layolle’s 5-part ‘Si ch’io la vo seguire nessun’altra offesa’, and both versions probably derive from an older source that may indeed be the music to which the LA766 incipit refers. The Layolle madrigal is ed. in D’AcconeMFR, iii, no. 19 (in the commentary D’Accone notes that it “uses a popular melody, albeit one of Italian origin, as a cantus firmus;” xiii). The same text was set by Cara, with music transmitted in Ve, no. 36, and PetF/xi (ed. in LuisiFr, no. 1, and PrizerCP, 449-51). Text & music of Razzi’s version ed. Mancuso, no. 75.
