Nobuo Uematsu is a bloody genius. I first heard this tune sixteen years ago and it hasn't left my head since. I've transcribed it by ear twice but it still completely mystifies me...
This is the "original" tune (actually my first transcription with square waves from a real gameboy)
This is my first try at it with GPO: Harpsichord, Violin, Viola, and Cello.
This is a different rendering using SIR reverb in response to some comments below.
Comments on production are very welcome, as I'm going to have serious trouble using this software for work and worship if all the instruments continually sound like they're playing in a phone booth.
