Scott's Super Scary "Symphony"

I had so much fun doing my Birthday "Symphony" that I decided that I should do another one. It's that time of year for scary stuff and this is what I find scary. So turn off the lights, turn up the sound, and hang on to your significant other.

I'm not going to tell you want this next one is because I want to see if you can guess. It will help if you close your eyes but if you still can't get it there is a HUGE clue at the end.
