I'm not a pro musician and don't know as much about music as I'd like to. But a couple of days back I heard an instrumental that took my sleep away. It was played on an electric, backed by, from what I could tell, bass and almost symphonic techno or something. Although I couldn't figure out what the song was called, I did manage to play the tune on a friend's guitar. Played on the thin e-string, these are the frets: -

1 4 6 8
8 13 11 8 4 8
8 13 11 8 4 6 8 9P8

It's something like this ... if someone out there can figure out which song this is, I'd be very grateful and may sleep peacefully for a change.
