Well, I'm not sure....
These short pieces seem to have been used to fill out a spare page (folio M2v). I present them here more as a matter of interest. Ho hum.
“A gigue” is rather jumpy and erratic, and I found it difficult to discern any pattern.
“Lantero” is a lively little piece, but I have yet to find the significance of the name. Good fun to play.
“Three parts in one upon an old ground.” To be honest, it’s not that easy to determine which note goes with which voice, even in the lute original. As to the ground, I do not recognise it. For the record, these are the (approximate) chord changes:
|G C A |G Dm |G C G C |F C |G Am D C |Dm Bm Am Bm |
|C G Am A |D G |A D | G Em Dm | C D | G ||
