Im too shy (or embarrased) to sit down and do a YouTube thing or similar..sorry..If you ever come up to Stockholm (from Poland),
I promise I will show you the piece and everything that Ive figured out from it..
There are a few places in the music where I cant tell 100% where on the neck V positioned it, but what I play sounds correct, its just that Im pretty sure if V ever sat down and played it, there would be some places where it is done differently.
You should try what I did, sit down with some kind of "amazing slow-downer" and do one phrase at a time, slowly you will get the hang of the voiceings and chords, and when youve nailed that little chord or flurry of notes, move on to the next etc.. It can be fantastic "ear training", but is it very time consuming.
quite rewarding in the end, you will come out a better musician with a better ear .
