In one of the towns today will be a concert of a famous rock band. You at Rock Music will help them with this. Before you on the screen you will see the playing field on which special multi-colored buttons will be located below. You will need to look carefully at the screen. Colored circles will crawl towards the buttons at different speeds. When one of them reaches the button, you will have to click on it. Performing these actions you will extract sounds, which will subsequently be added to the melody.
