This is a contrafactum setting of Josquin’s five voice chanson Je ne me puis tenir d’aimer (Josquin, Wereldlijke Werken, no 31), NJE 29.11. Mudarra’s is the only version of the piece with the “Respice in Me” text, derived from the Introit for 3rd Sunday after Penecost. The same music is found in Fuenllana with the text Lauda Sion.(Fu061) and also attributed to Gombert. A polyphonic setting of this Lauda Sion is found in Archivo Falla 975. For the stemma, sources and a transcription of the chanson (see blackburn1976; Jacobs1982, 204, nº57. Jacobs gives another version with the same music. Mudarra’s version is virtually identical to the vocal model (roa2015) which is reprinted in vol. 29 of the New Josquin Edition and in the Smijers edition as Wereldlijke Werken, Bundel III (Amsterdam, 1925), No. 31. Roa reports there is a 4-part version of the piece in Odhecaton C, with the same text but different music (roa2015). A complete list of sources is on DIAMM: https://www.diamm.ac.uk/compositions/26954/

Mudarra and Fuenllana both independently attribute the music to Gombert, perhaps because of the five voices. In Mudarra’s version the second tenor (quinta vox) is the texted voice.
