Music and sound effects
Adding music and sound effects to your web page can make the navigation more pleasant. The audio formats that you can include in HTML documents are midi (those with extension .mid) and the .wav. If you have already threaded with these audio formats you have probably noticed that they are not compressed formats, therefore make attention not to include too many audio files or you will slow down your users' connection. 
Netscape Communicator interprets the < EMBED... > TAG. Internet Explorer instead previews the use of < BGSOUND... > TAG. To be sure our documents will work correctly with both the browser we will use both the tags in each page. The first one will not come recognised by Internet Explorer and therefore it will ignore it, Netscape Communicator from its part will make the same thing for the second TAG. 

Supposing we have an audio file music.mid we will write 


<BGSOUND SRC="music.mid" LOOP=infinite> 
<EMBED SRC="music.mid" HIDDEN=true> 


The LOOP parameter, set to infinite, indicates to Internet Explorer to restart when the music ends. The HIDDEN parameter, instead indicates to Netscape Communicator not to visualise the control panel for the audio file management.

Arranging the proposed code with the events onMouseOver and onClick, it is possible to add sound effects generated by the way the user moves the mouse in the web page. Here we have realised an image-link with a sound effect.

Finally, in order not to slowdown the page visualisation, I suggest you to posizionare the sound TAGs at the end of the document, just before the </BODY> TAG. In this way the client will start loading audio files after all the other objects on the same page.
