OK I found this tutorial and I thought it was cool. http://www.instructables.com/id/How-to-Make-LEDs-Flash-to-Music-with-an-Arduino/?ALLSTEPS
 It works as is but I wanted to add more leds. I saw at the top it had more beat types it could listen for so I added them to the code but now I'm running into an error. It keeps telling me there are too many "{" without a "}" to match it. Could someone help me? thanks and heres my code. Theres two sections to it a beatwrite and a beatlisten so Im gonna post both.

/**
  * This sketch demonstrates how to use the BeatDetect object in FREQ_ENERGY mode.<br />
  * You can use <code>isKick</code>, <code>isSnare</code>, </code>isHat</code>, <code>isRange</code>,
  * and <code>isOnset(int)</code> to track whatever kind of beats you are looking to track, they will report
  * true or false based on the state of the analysis. To "tick" the analysis you must call <code>detect</code>
  * with successive buffers of audio. You can do this inside of <code>draw</code>, but you are likely to miss some
  * audio buffers if you do this. The sketch implements an <code>AudioListener</code> called <code>BeatListener</code>
  * so that it can call <code>detect</code> on every buffer of audio processed by the system without repeating a buffer
  * or missing one.
  * <p>
  * This sketch plays an entire song so it may be a little slow to load.
