+<a name="sounds-events-play" />
+
+#### ```play``` event
+
+The ```play``` event will be fired when the sound is played.

+var sound = new Pizzicato.Sound();
+
+sound.on('play', function() {
+  //...
+})
+```
+
+
+<a name="sounds-events-pause" />

+
+Fired when the sound is paused. For example:

+```javascript
+var sound = new Pizzicato.Sound();
+
+sound.on('pause', function() {
+  //...
+})
+```
+
+<a name="sounds-events-stop" />

+#### ```stop``` event
+
+Fired when the sound is stopped. For example:
+
+```javascript
+var sound = new Pizzicato.Sound();
+
+sound.on('stop', function() {
+  //...
+})
+```
+
+<a name="sounds-events-end" />
+
+#### ```end``` event
+
+Fired when the sound has ended. This is only valid for sounds coming from a file. For example:
+
+```javascript
+var sound = new Pizzicato.Sound();

+### Memory management
+
+When creating large numbers of Pizzicato objects you may experience a tipping point after which all sounds in the site are muted. This can vary depending on your browser, operating system and computer running the code.
+
+To release some of the load, you can call the ```disconnect``` function on the Pizzicato.Sound objects no longer in use. This will disconnect them from the context's destination and they will become orphaned graphs, which will be freed when necessary.
