Through composed setting of four verses of poetry. It is in four voices, this time with the vocal line incorporated into the tablature as well, given the poyphonic and imitative nature of the composition. Labelled as a “soneto”, the structure of the verses could legitimately be the opening quartet of a sonnet or, as Pujol speculates, perhaps some elegaic verses in honour of Isabel of Portugal. In Pujol’s commentary he says “The allusion to the Tagus and to the soul ‘per che l'orbe ttttto geme’ leads us to suppose that this sonnet is related to the death of the Empress Isabel, which a Spanish poet, in the time of a Balthasar Castiglione in Spain, could easily have written in Italian.” (Pujol1949, 83).
Roa comments on the extensive use of imitation in the piece and compares the texture to that of a fantasia. He also speculates, without foundation, that the piece may be of earlier composition.
