Rubric: “This fantasia has to be played according the tempo, because it is contrrapuntal. Second level [of difficulty]. Mode 5.” This is another polythematic imitative fantasia of a brief short 79 compases, with characteristic lack of polyphonic rigour. It is charming and vivacious, but rather facile, beginning with 2 voice canon of theme 1, then somewhat freer counterpoint with several statements of theme 2 interwoven with varying degree of rigour in the way that Valderrábano makes his melodious free textured style. From c. 42 various motives are introduced that emphasise upward motion in seminima values, particularly in lower part. At c. 63 theme 2 is reintroduced, canonically treated until c. 70, where a classic example of the “Valderrabano long arch” forms the cadence. The recurrence of theme 2, and similarity throughout shows total unity of concept.

Valderrábano makes no declaration that this fantasia is based on another by Francesco da Milano. This discovery was made by American lutenist Dick Hoban and communicated to me in an email (19/09/1996): He indicates that a “close comparison of Francesco's fantasia #65 and Valderrabano's fantasia #13 will demonstrate that the former was a significant source for musical material parodied in the latter. Valderrabano quotes Francesco's work no less than six times and uses the quoted musical material in the exact sequence in which it is found in the model. In one instance, the quote runs for 8 bars with the average being 4 bars. Frequently, the quotes run note for note. The effect of his extensive and sequential use of the source musical material gives the impression that Valderrabano was tightening the development of Francesco's fantasia structure. The quoted material is all found in the first half of Francesco's fantasia”
