Currently, the boundary between music and the visual arts is collapsing, with many attempts to combine these two fields. Some basic elements shared by both connect music and visual arts. Basic music elements such as note, rhythm, and pitch can be compared to basic visual elements such as dot, line, and side, which can be used to express the feeling of music by using form, color, and texture.

In this study, I focused on expressing music visually by using basic shapes of mathematical properties, and I tried to make an experimental interface that organizes musical sound, chord and rhythm in a mathematical system. This project is a new way to express musical sound visually.

Also, it creates curiosity, especially among people who do not have specialized musical training, since using this method does not require extensive instruction, as learning to play traditional musical instruments does, but instead offers a simple and easy way to play music by using basic shapes.

Harmonia came from Pythagorean principle of Harmonia believed that each element was structured by a different harmonia: earth is a cube, fire a pyramid, water an icosahedron, air a triangle. The world was not dominated by forces, but rather arranged in an orderly and structured (mathematical) way. Basically everything has a mathematical form.That principle can certainly be applied to my sound visualization's fundamental concept.
