Sound in Frames
To have music play when a page is loaded <BGSOUND SRC="yoursound.mid" loop="1"> is included in the HTML source.
This is also true if the page is loaded into a frameset. The problem here is that when another page is loaded the music will stop unless you have the music reload with the new page.
This will also mean that the music will start from the beginning, which would be a bit irritating having the same music restart at the beginning of every page that is loaded especially if it is a short page.
One solution is to include the BGSOUND SRC in the frameset file this way the music would continue playing even if a new page is loaded into your main frame.
<BGSOUND SRC="yoursound.mid" loop="1">
