  2  * This porgram interprest melodic lines given in ABC notati nas a chromesthete might.
  3  * 
  4  * A Pitch class will be defined, and will take center stage in processing.
  5  * 
  6  * INterpreting a molody in aBC notaiton will amount ot flashing colored rectangles
  7  * for prescrived durations, while sounding the Pitch! The color of the rectangle
  8  * will correspond to pitch class. The duration will correspond to the duration of the note.
  9  *
 10  * For this second  version of the program, the duratin will be held constand at 1 beat.
 11  * 
 12  * Threee sorts of images will appear on the screen, the chromestheic output box,
 13  * a text input box, and an error message box. Simplicity of design is rendered
 14  * by premitting only one box to be on the screen at a time. 
 15  * 
 16  * ABC represents notes in a manner consistend with these examples,
 17  * C, D, E, F, G, A, B, C D E F G A B c d e f g a b 
 18  * 
 19  * Google ABC music represtnation if you would like to know more about it.
