This is a charming, melodic little piece, and good fun to play. The there is a statement of the main theme in bars 1 – 16, followed by a variation in bars 17 – 32; these are both in the style we are used to in lute transcriptions. The third variation is in campanelas style: sounding like little bells.
I have posted two versions: one for re-entrant uke, which (especially in the campanelas) should sound quite like the original, which was written for re-entrant guitar. The low-G uke version makes some use a bass line, but this necessitates playing the high G on string 2 where the melody demands, and makes the campanaleas somewhat more convoluted.
I have little else to say about the piece, except that the falling scale fragment in bars 26 to 28 sounds really Spanish to me.
I hope that you enjoy playing it.
Note added 10/2/18: This is an updated version of the original post, with two revised arrangements. If you have the earlier version you might like to replace it.
