This is a transcription of Nobuo Uematsu's Prelude 
from Final Fantasy VII (standard tuning).
The tab is all my own work.

Repeat from start.

The parts within /^^^\ are played one octave higher. 
This can be accomplished by using an octave pedal,
or by playing those notes with pinched harmonics 
(pinching half way between the fret you are holding 
and the bridge).

Note: You'll notice that some notes are bracketed. 
These are the notes that represent the overlying 
melody in the tune. I have tabbed them in that way 
as it is theoretically possible to play both the run 
and the melody at the same time. Feel free to ignore 
the notes in brackets if you were just after the 
run, or vice versa. I know i can't play both at the same time.
