I've also written out a version of this song in F#m, when you feel like trying a bar chord- see my List of Songs for Guitar.
When I play this song, I use a soft finger-picking pattern at the start : B132, 4132 with some variations as I go, then for the more dramatic verses I strum with my fingers in this kind of pattern ( v = down stroke, ^ = upstroke):
V ^ v ^ v ^ v ^ V v ^, ^ v (^) V ^ v ^ v ^ v ^ V v ^, ^ v (^)
- And in the na-ked light I saw, - ten thou sand peo-ple may-be more-
It’s really a case of listening to the recording and getting an idea of the rhythm and backing style, then playing around with finger-picking and strumming until you get something that sounds OK to you. Lots of practice!
