1    /* For this first version of the program, the duration will be held 
2     *constant at 1 beat. 
3     *Three sorts of images will appear on the screen, 
4     *the chromesthetic output box, a text input box, 
5     *and an error message box. 
6     *Simplicity of design is rendered by permitting only one box to be on the screen at a time. 
7     * ABC represents notes in a manner consistent with these examples: 
8     * C, D, E, C D E c d e 
9     *Google ABC music representation if you would like to know more about it.
