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 finishing 
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 the first version of the program, the duration will be held constant at 1 beat. 
14    * 
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 the three examples: 
21    * A, A a B, B b C, D, E C D E c d e F, F f G, G g 
22    * 
23    * Google ABC music representation if you would like to know more about it.
