Piano Chord Calculator

JavaScript can create all sorts of unusual calculators
This calculator script is rather specialized in what it does and will probably only be of interest to piano teachers (as an actual calculator). It does make use of several rather unique Javascript coding techniques such as Drawing with CSS, Passing multiple values in one form field, Multi dimensional arrays, and How to test stylesheet colours. See how I managed to combine all of these together to produce the Piano Chord Calculator.
