Frescobaldi Capriccio di obligare di cantare la quinta parte

[Gervais Frykman]

This was published in 1624. My fellow contributor has posted Frescobaldi's other piece in this manner, the Recercar con obligo di cantare la quinta parte senza toccarla from Fiori Musicali of 1635.
I wonder whether this should have a page to itself, or do you think that the unusual genre is a reason for including both on one page.
Thank you
