1    /* 
2     *This program interprets melodic lines given in ABC notation as a 
3     * chromesthete might. 
4     * 
5     * A Pitch class will be defined, and will take center stage in the 
6     * processing. 
7     * 
8     * Interpreting a melody in ABC notation will amount to flashing 
9     * colored rectangles for prescribed durations, while sounding 
10    * the pitch! The color of the rectangle will correspond to pitch 
11    * class. The duration will correspond to the duration of the note. 
12    * 
13    *the duration options will be 1 beat, 2 beats, 3 beats, 1/2 a beat, 1/3 a beat, and 2/3 a 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
