The upper melody of this piece corresponds closely to the melody of the estribillo of the villancico by the Portuguese composer Escobar in CMP, Cancionero de Elvas, and CMBL. The text is by Garci Sánchez de Badajoz. Additional copies of the polyphony: Cancionero Musical do Bibl. Nac. de Lisboa (ed Morais) Vilancetes, Cantigas… No XX. It is the same melody as the CMP (with minor variation) setting by Pedro de Escobar (p. clxvi-clxvii) Pujol numbers the work as Soneto XXII (pujol1965).
