Variation on the harmonic formula of the “zarabanda”. This appears to be among the earliest known sources. The earliest dated source is Monstesardo’s guitar book of 1606. The zarabanda had been mentioned in literary sources from the early sixteenth century, but the associated ostinato formula seems to have consolidated around 1600. The formula is of four bars: I - IV - I - V | I - IV - I - V- I | but the tablature is divided into 8 bar units divided by double bar lines. This piece survives in the manuscript additions to Silva de sirenas in Vienna, Österreichische Nationalsbibliothek, S.A.76.A.15.
