Guild Wars 2

Hello everyone that will be reading this desperate post,

I am not a musician.
I do love one artist, Ryuichi Sakamoto.

I need help creating a sheet music or something that will help me play that music, at least the main part of it. I’ve done a lot of this in Guild Wars 2.. Thought of buying myself an instrument for the first time because I really wanted to share that beautiful song to my fellow guildmates and players around me;

Forbidden Colors – Ryuichi Sakamoto.

I don’t know what I would do to whoever will help me with that song.
Well if you have spare time, have a look at it and help out another player out there !
