Maybe you don't dance well yourself. Maybe a certain dance can be manipulated to fit many types of music...many songs...
This tool is a space online where you can control the animation of an animated danceer. Moving the dial up and down, you control the speed of the dancers movement...and you control the song which is playing...therefore you get different perceptions of the music and how to feel it (the dancers movements slow and fast...subtle and abrupt..) expressing the music differently......
