Just watch and listen. The music is in fact powered by the progress of the fractal. I tried to illustrate that with the dots.
Well here it is... my quasi-special 50th project. It's a combination of my Sierpinski Triangle project and my Pachelbel's CaNNon project. I tried to line up the colors of the background with the joints of the triangle. Hehe why did I make this?? I guess I just really like music and fractals. Here's a weird thought: imagine what it would be like if every time you drew a fractal like this, awesome piano music would play...! This project is a combo of https://scratch.mit.edu/projects/86163526/ and https://scratch.mit.edu/projects/102445503/ both by me. Oh and also https://scratch.mit.edu/projects/105790128/ as well.
