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