How do I mimic the piano in Everywhere at the end of time

I am attempting to make a song that mimics Everywhere at the end of time, being 6½ minutes instead of being 6½ hours, it will involve piano that resembles the piano in A2 (We don't have many days) and F2 (Drifting time misplaced) but I cant find a way to find a soft piano, is there a soft piano in the instruments, or is there a way to soften a piano sound
