this version shares quite a bit in common with the Uppsala version (uppsala1556, no 29), although it might not be the same. Further investigation required. Not the same as the other versions of the vihuelists, but clearly using themes closely related to the Fuenllana version attributed to Vásquez.

Based on the inpublished comparison made by Gracia Gil (e-mail communicated by 2/9/2012) the known settings appears to use a commonly known melody that was used by Carreira (Coimbra), Narváez, Pisador. Fuenllana, the anonymous setting in the Cancionero de Uppsala, and Vásquez, Recopilación. The melody in the Valderrábano setting is the only one that does not conform.
