# Play tones
# If you click mouse (left click) on screen, then Python will play music for you
# Press buttons to play individual tones.
# To keep simplicity, could happen, that pressed button will play two tones. Fix it, if you like.
# Attention!! Random tones could be very annoying to people around you :)
