I transcribed this a couple of months ago as it seemed a slow, manageable and beautiful piece for someone new to classical guitar such as myself. And indeed it largely is, though it takes a careful, sensitive guitarist to make it sing. Note that I haven’t scored the second movement because it seemed beyond my ability to play.
I haven’t included fingering as I personally like to do that myself as I learn a piece, and hate when a score comes cluttered with annotations. Musically, the guitar score is essentially the same, but one tone higher, and with the sixth string tuned to D. I removed the glissandi on the pizzicato chords as that seemed impractical on the guitar. This is the most substantial difference between the original version and the transcription.
I was slightly irritated to find that some other guitarist had gotten there first in playing Ligeti’s Cello Sonata on guitar. However, he’s not giving out a free score, so this should post should be of use to someone.
And if you’d rather just look at it on this page, here’s the score in image format:
