Songs number 15 and 16 and 19-21 seem to be irretrievably lost.  17 and 18 are reconstructed from a manuscript source (Christ
Church, Oxford MS 439, pp. 1 and 80), consisting of a melody line with words and a bass line only.

I started with the Thurston Dart version for harpsichord and went on from there to make a lute version.  If anyone has a better
version, let me know.
