Background Sound
Although it is possible to embed an audio file on a web page so that it starts playing automatically when the page loads, this technique is not recommended. The problem with background sounds is that users have no way of turning the sound off if they do not like it. Also, if the audio file is large, you are forcing a potentially lengthy download on the user. Furthermore, background music on a web page is almost always unnecessary.
If you do need to add a background sound to a page, you can do it with this nonstandard markup. Be aware that this element will cause your document not to validate.
