To set the string in motion, click "Center Pluck" or "Fundamental", or click on the string.
Below the function 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.
Note: the sound has only been tested successfully on Windows. On linux it doesn't work and on the Mac it is hopelessly delayed. Also if you are using Netscape 6 or the Sun Java plug-in you won't be able to load the applet at all (using the sound classes causes a security exception). In that case you can use this version of the applet, which has the sound code removed.
