The mute button is hard to see. Suggest you make the music off by default, and let people switch it on if they so choose.
I agree that the chirping is strange and is confusing -- it does not obviously evoke photography, weddings, or anything else about your value proposition. If I opened this site and I suddenly heard chirping, I would wonder whether a pop-up had opened, or whether I had the wrong site. By contrast, if you make the music opt-in, then it will start when I click the "play" button, which at least associates the sound with a user action.
