Need help cleaning up some sheet music on a PDF file

[blacky111222333]

So, I found this awesome song that I wanna learn but there's no sheet music on the internet unless you wanna pay $15, so I emailed someone on Youtube and they sent me the file attached below. It's not very clear and hard to read after printing so I was wondering if there was a way to clean it up(get rid of the bluryness).

There are no 'magic tools' that allow you to remove all blur in one click ...
You might want to use something like 'Blank Sheet Music Maker', which allows you to recreate it.

You could use some generic image software like Photoshop to sharpen it, should help a bit. Though if that's all there is to it, you might as well rewrite it.
