When music written for vihuela or lute is arranged for ukulele, there is some loss in the bass as the vihuela/lute has 6 strings while the ukulele (or Renaissance guitar) only has 4 strings. I do have to figure out the harmonies/chords to try to preserve what the composer intended but with a smaller range of notes.
Is anyone interested in arrangements that preserve the 6 string configurations? In other words, I would be arranging the music for vihuela, lute, or guitar with an F# tuning for the third string. Mel Bay has already done this with all 40 Fantasias in Milan’s “El Maestro” where all the music is transcribed/arranged for 6-string instruments. There are others who do this as well for individual pieces, but you have to hunt for them.
