Visualising Sound - Melody Chord and Rhythm

I came across this app that has been developed which visualises individual elements of a song based on either the melody, chord and rhythm. This app is aimed towards people looking to investigate individual elements of specific rock songs but the way they have visualised each element of the song creates a nice link between sound, shape and colour. 

This would require me to use a music based piece of software such as Logic, so that I can find the shapes of the sound waves that each element of a song creates. This would also mean that I would have to find examples of songs that are still in an editable format, so that I can pick and visualise each instrument that is being played, However it may be worth experimenting with,

This was of visualising sound, could be a little too generic though and as my main aim of this brief is to experiment with interesting visual creation techniques.
