Program: RoBach
Description: When this program is started, it will ask the user for a musical key and the beats per minute they would like the program to play at. Once the user inputs this information, the program will start playing random notes and chords at random lengths in the scale chosen by the user. Note that a third party program that emulates an instrument playing by the keyboard is required for this to work.
