This is a custom mix(?), I suppose, of the 19th track of the Fate/Stay Night: UBW soundtrack album II. Sections A and B are based off of the ensemble sheets by Jim Tian from the Kenji Kawai version, available here: https://ichigos.com/sheets/210. The Kenji Kawai song is available here: https://www.youtube.com/watch?v=Zfx8-c63u0Q. Section E is essentially the same as Section B, but with the left and right hands switched. Section C, D, F, and G are on some level transcribed from the original song by Hideyuki Fukasawa, available here: https://www.youtube.com/watch?v=1ErwgLxBNL0. Regrettably, I couldn’t find a way to add the synth in without making it impossible to play, so it may sound a bit empty without it, hence the optional pedal to give a smoother feel (recommended more for the chords in the beginning, which were originally string quartet & violin). As always, enjoy.
