<br />
is approximately the note: <b id="note_name">note_name</b>


<br />
<div id="staff"></div>
so it has the harmonic series that starts off with the notes:<br /><span id='html_display_of_notes'></span><br />

<script src="grand_staff_harm.js"></script>
<script>grand_staff_harm.init();</script>

</div>
