1 /* 2 * This program interprets melodic lines given in ABC notation as a chromesthete might. 3 * 4 * A Pitch class will be defined, and will take center stage in the processing. 5 * 6 * 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. 7 * The duration will correspond to the duration of the note. 8 * 9 * The duration will be held constant at 1 beat. 10 * 11 * These sorts of images will appear on the screen, the chromesthetic output box, a text input box, and an error message box. Simplicity of design is rendered by permitting only one box 12 * to be on the screen at a time. 13 * 14 * ABC notes represent these examples: 15 * C, D, E, C D E c d e 16 * 17 * Google ABC music representation if you need help. 18 * 19 * By Hunter Gersitz | SUNY Oswego Fall 2019 20 * */ 21 22 package chromesthesia2;
