Play multiple sound at the same time

Using HTML 5, I want to play multiple sounds simultaneously. how can I do it?

Here's what I currently have:

<audio controls="controls">
    <source src="audio/(TESBIHAT).mp3" type="audio/mpeg" />
    <source src="audio/Dombra.mp3" type="audio/mpeg" />

    <embed height="50px" width="100px" src="audio/(TESBIHAT).mp3" />
    <embed height="50px" width="100px" src="audio/Dombra.mp3" />
</audio>
