I've been searching for a way to inject some jQuery into my squarespace site so that a certain audio file would play depending on the vertical position the visitor was at. 

My site is where I post short stories, and the specific reason I would like to use this on my site is I would like background music to play different sections of music as people scroll down to read more.

After searching around the internet for a while I ended up finding a similar thread on this site ( here), and have essentially deemed it the holy grail of being exactly what I'm looking for.

However, here's my problem: I'm terrible at jQuery and can't utilize the code from that other thread to meet my needs. So, I was hoping that someone here could walk me through the code and how I can adapt it to be used for what I'm looking for.

I've tried to go through a few online classes to learn how to better use jQuery, however this is the only thing I've wanted to do with jQuery so got a little bit antsy haha.

The full code is here:  http://pastebin.com/fizVzW3B

Please let me know if there's any more information I can provide to help with this.

Thank you!
