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. 21 */ 22 package chromesthesia2;
