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 duration, while sounding 
10    * the pitch! The color of the rectangle will correspond to 
11    * the pitch class. The duration will correspond to the duration 
12    * of the note. 
13    * 
14    * For this first version of the program, the duration will be held 
15    * constant at 1 beat. 
16    * 
17    * Three sorts of images will appear on the screen, 
18    * the chromesthetic output box, a text input box, 
19    * and an error message box. Simplicity of design 
20    * is rendered by permitting only one box to be on the screen 
21    * at at a time. 
22    * 
23    * ABC Represents notes in a manner consistent with these examples: 
24    * C D E C D E ,cde 
25    * 
26    * google ABC Music representation for more information
