The program is designed to help you master the basic knowledge of music theory needed to play the accordion and learning the game on the right keyboard.
Program features:
 - Training of musical intervals;
 - Training notes;
 - Exercise the right to play the keyboard (range, random notes, only the white keys, a certain octave, all keys);
 - Play music from the midi-files (as included in the program, and added to the library);

Before each exercise is a brief reference to the theory.
