/** This program interprets melodic lines given in ABC notation as a* chromesthete might.*
 * A Pitch class will be defined, and will take center stage in the* processing.*
 ** Interpreting a melody in ABC notation will amount to flashing* colored rectangles for prescribed durations,
 * while sounding* the pitch! The color of the rectangle will correspond to pitch* class. The duration will correspond to the duration of the note.
 */

//for first version of program the duration will be held at one constant beat
//three sorts of images will appear on the screen:
//chromesthetic output box, text input box, and error message box. only one will appear on the screen at a  time

//ABC represents notes in a manner consistent with these examples: C, D, E, C D E c d e
//google ABC music representation if i want to know more about it
