Can music look good? Yes!
Music can be visualized using an oscilloscope. Most music is pleasant to look at but may appear quite chaotic. You can make an effort to create the music that looks the way you want it to if you know how. The samples below can be used as a base for creating your own good looking music. By playing around with harmonies you will get different patterns, and you can achieve complex structures such as moving 3D objects by modulating the signal.
