1    /*This program interprets melodic lines given in ABC notation as a 
2     * chromesthete might. 
3     * 
4     * A Pitch class will be defined, and will take center stage in the 
5     * processing. 
6     * 
7     * Interpreting a melody in ABC notation will amount to flashing 
8     * colored rectangles for prescribed durations, while sounding 
9     * the pitch! The color of the rectangle will correspond to pitch 
10    * class. The duration will correspond to the duration of the note. 
11    * 
12    * For this first version of the program, the duration will be held 
13    * constant at 1 beat. 
14    * 
15    * Three sorts of images will appear on the screen, the chromesthetic 
16    * output box, a text input box, and an error message box. Simplicity 
17    * of design is rendered by permitting only one box to be on the screen 
18    * at a time. 
19    * 
20    * ABC represents notes in a manner consistent with these examples: 
21    * A,B,C,D,E,F,G, A B C D E F G a b c d e f g 
22    * 
23    * Google ABC music representation if you would like to know more about it
