Where should you place a "background sound play button" on an illustration site

I have a site which has many illustrations. I would like for there to be sound but the browser doesn't allow you to autoplay sounds. So at some point the user has to click.

I also have a second sound, the reading of a poem. I would somehow like for there to be a button or some way of turning on the poem audio.

What are some design UX ideas for accomplishing this without just plastering a > play button on the screen? For both the background sound, and the poem narration.
