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    * For this first version of the program, the duration will be held 
14    * constant at 1 beat. 
15    * 
16    * Three sorts of images will appear on the screen, the chromesthetic 
17    * output box, a text input box, and an error message box. Simplicity 
18    * of design is rendered by permitting only one box to be on the screen 
19    * at a time. 
20    * 
21    * ABC represents notes in a manner consistent with these examples: 
22    * C, D, E, C D E c d e 
23    * 
24    * Google ABC music representation if you would like to know more about it.
