HTML 5 Canvas: Music notation

Try the demo.

FireFox 3.6.3:

<pre id="line58">  <canvas id="notation" width="800" height="400"
    style="background: #eed; padding: 10px; border: 10px solid #ddc">
    HTML5 Canvas not supported on this browser.
  </canvas>
</pre>

Maybe this is something for Wikifonia?
