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 processing. 
6     * 
7     * Interpreting a melody in ABC notation will amount to a flashing colored 
8     * rectangles for prescribed durations,while sounding the pitch! The color of the rectangle will correspond to pitch class 
9     * The duration will correspond to duration of note. 
10    * 
11    * For the first version of the program, the duration will be held 
12    * constant at 1 beat. 
13    * 
14    * Three sorts of images will appear on the screen, the chromesthetic output box, a text input box, and an error message box. 
15    * Simplicity of design is rendered by permitting only one box to be on the screen at a time. 
16    * 
17    * ABC represents notes in a manner consistent with these examples: 
18    * C, D, E, C D E c d e 
19    * 
20    * Google ABC music representation if you would like to know more about it.
