OST 11 Demo loop - "I have no mouth and I must scream" piano (attempt) !!!

Music is probably by John Ottman, the composer of music in the original game.
My best friend recently introduced me to this thingie, and I really enjoyed its lore, and music.
:D
(i barely know how to write notation, so do not expect piano midi or notation, however I will try)
Also how do I play piano, I, unfortunately, don't have 3 hands TwT
