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 flashing 
8     * clolored rectanglegs for prescribed durations, while sounding the 
9     *  pitch! the color of the rectangle will correspond to pitch class. The duration will 
10    * correspond the the duration of the note. 
11    * 
12    * for this first version of the program the duration will be held at constant at 1 beat. 
13    * 
14    * three sorts of images will appear oon the screen, the  chromesthetic 
15    *  output, a text input box, and an error message box. Simplicitly 
16    * of design is rendered by permiting only one box to be on the screen at a time. 
17    * 
18    * ABC represents notes in manner consistent with these examples: 
19    * C, D, E, C D E c d  e 
20    * 
21    * Google ABC music representation if you want to know morea bout it.
