How to add music to a Salesforce Visualforce Page?

Hello,

There is no visualforce custom tag that wraps playing media, or the HTML5 media tag types.

I would suggest vanilla HTML for doing this as per the documentation here:

http://www.w3schools.com/html/html5_audio.asp

In your case, you'd just want the URL to point to a resolveable URL, whether hosted in: A static resource
Some kind of content in Salesforce (attachment, chatter feed, etc.)
An external URL from a CMS, CDN, or whatever
Given your requirement of playing a single audio file I would use a zip static resource with several different files in it, so you can support as many browsers as possible. You'd then end up with something like this:
<audio controls>
  <source src="{!URLFOR($Resource.AudioFiles, 'NewPage.ogg'}" type="audio/ogg">
  <source src="{!URLFOR($Resource.AudioFiles, 'NewPage.mp3'}" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
If it were dynamic, I'd probably bind the src to a field that output some kind URL pointing to the file. My first choice would then use a formula field or some Apex to populate the value. If the dynamic value was not dependent on data in Salesforce, then I'd fall back to Javascript, most likely.

Thanks.
