To set the string in motion, click "Center Pluck" or "Fundamental", or click on the string.
Below the string you will see a graph showing each normal mode's contribution to the string's vibration. There are two sets of bars; on top are the magnitude bars, which shows the amplitude of each normal mode. These bars can be adjusted with the mouse, or you could double-click on one to isolate a particular mode.
If you get a message Security exception, use nosound version, then you can use this version of the applet, which has the sound code removed.
