About playing music automatically - not recommended
It can be tempting to add music that plays automatically when a visitor arrives on your page. As tempting as it might be, always remember that just because you’d like to control the environment of a site visitor, they may have other ideas.
Websites are a visual medium, and a lot of web surfing takes place under conditions that aren’t suited to music: from mobile browsers on a train or bus, from work or school. And a lot of web surfing that takes place at home is already accompanied by other activities, which can include listening to music: people often listen to their own choice of music on their computers or stereos while they surf the web.
Imposing music on people when they display a page on your website often results in unintended consequences: people don’t necessarily like to be disturbed with music when visiting websites or listening to music over the top of whatever else they may be listening to while they surf.
If you do want to add an auto-play feature to music on your site, you can: either by creating it directly on the player's website (like this one for example), or editing its code to add the relevant auto-play code for that player.
Just bear in mind that doing so may wind up causing more harm than good: it’s always best to let a visitor decide whether or not to add sound while they visit your site pages.
