Not terribly complicated, but still a challenge
I always like to have the melody of a piece in my mind when playing it – otherwise I just get lost. On a lute played by an expert you have a lovely wall of sound, but on the ukulele any deficiencies in interpretation can be just a mass of plonks.
There are three strains. I have not even attempted to transcribe Dowland's variations as they are heavily ornamented.
The upper voice of this galliard is not one you would find the under-butler whistling after hearing a performance in your salon. I have played a MIDI version of it over and over in a not wholly successful attempt to fix it in my head.
Don't let me put you off, though. You can download
1. The fullest transcription that I can make here,
2. A much simplified arrangement with an emphasis on the upper voice here.

Giles Hoby was a member of the landed gentry in Herefordshire and Gloucestershire. I have no idea why the galliard received his name.
