4    This program interprets melodic lines given in ABC notation as a 
5    chromesthete might. 
6    A Pitch class will be defined, and will take center stage in the 
7    processing. 
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   * 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   * C, D, E, C D E c d e 
22   * 
23   * Google ABC music representation if you would like to know more about it.
