Rate of the Music

Another thing that the music represents is a heart rate machine and the rate at which a heart beat can go. The Animation could be a series of line that look like the heart rate monitor lines and images. The could glow in different colours when the music represents different moods. There could be different lines that represent different 'characters' with different moods. The lines could also start to make shapes such as a person running or racing inside the heart rate lines. There could also be other shapes inside the line at different points in the music once a narrative is decided.
