how to add background music to a web page with audio toggle?

I am using bootstrap to build my website and I would like a little bit of flare added to it. I have read some stuff on here but couldn't find exactly what I want.

1. glyphicon-volume-up to right of the navbar-header.
2. music autoplay once site visited
3. volume default to 50%
4. switches between glyphicon-volume-off/glyphicon-volume-up (unmute and mute)

Here is my temporary website: http://ift.tt/22QpkI4

I hope that I am clear enough. I am still a newbie to a lot of things. Hope you guys can help this newbie out a bit. Thanks!
