/**
* <p>The web is much more than just canvas and p5.dom makes it easy to interact
* with other HTML5 objects, including text, hyperlink, image, input, video,
* audio, and webcam.</p>
* <p>There is a set of creation methods, DOM manipulation methods, and
* an extended p5.Element that supports a range of HTML elements. See the
* <a href="https://github.com/processing/p5.js/wiki/Beyond-the-canvas">
* beyond the canvas tutorial</a> for a full overview of how this addon works.
*
* <p>Methods and properties shown in black are part of the p5.js core, items in
* blue are part of the p5.dom library. You will need to include an extra file
* in order to access the blue functions. See the
* <a href="http://p5js.org/libraries/#using-a-library">using a library</a>
* section for information on how to include this library. p5.dom comes with
* <a href="http://p5js.org/download">p5 complete</a> or you can download the single file
* <a href="https://raw.githubusercontent.com/lmccart/p5.js/master/lib/addons/p5.dom.js">

* Scores are a JSON object with instruments at the top level
* and an array of time and values. The value of a note can be 0 or more
* parameters.

* The only requirement for the score format is that the time is the first (or only)
* value in the array. All other values are optional and will be passed into the callback
* function registered using `Note.route(channelName, callback)`.
* <br><br>
* To convert MIDI files to score notation, take a look at utils/MidiToScore.js
*
* @example
* //an example JSON score which sets up events on channels
* var score = {
* "synth" : [["0", "C3"], ["0:1", "D3"], ["0:2", "E3"], ... ],
* "bass" : [["0", "C2"], ["1:0", "A2"], ["2:0", "C2"], ["3:0", "A2"], ... ],
* "kick" : ["0", "0:2", "1:0", "1:2", "2:0", ... ],
* //...
* };
* //parse the score into Notes
* Tone.Note.parseScore(score);
* //route all notes on the "synth" channel
* Tone.Note.route("synth", function(time, note){
