Yes, of course you know this already - but sometimes it helps to actually see the fingering for the most common keys. Just a reference which I hope you may find useful.

Cavatina, by Stanley Myers and used as the main theme in "The Deerhunter", was originally arranged by Australian guitarist John Williams for two guitars. Either in the two-guitar or the later single-guitar arrangement it is often beyond the ability of most amateurs to play – me included. So I looked at a number of arrangements which are available and decided to make my own based partly on what I had seen but rationalised to broaden its playability to a wider group. 

There are five files available, all free to download. Two are the soundtracks 

- the full piece (cavatina.mp3)

- the backing track (cavatina_backtrack.mp3) 

while the other three files are the notation/TAB files for 

- the full arrangement (cavatina_full_arrangement.pdf)

- the solo arrangement (cavatina_solo_arrangement.pdf) 

- the 2nd guitar arrangement (cavatina_2nd_guitar_arrangement.pdf) 

so you can take your pick as to the way you wish to play the piece.

My arrangement is by no ...
