My project: https://editor.p5js.org/rl4800/sketches/isXwG1QuD
I made 9 images based on my imagination of what would sound and music look like when transferring them into patterns. It is a set of visible music.
Some explanations of my images:
Pic 1.2.3.4.6: visible sound waves
Pic 5: notes that fall on the staff notation
Pic 7: Piano
Pic 8: music player
Pic 9: a pretty common kind of drum beat
Drawing by hand could easily draw some irregular shapes, but people would probably spend much time repeating the same action. Computer drawing is hard to write complex shapes, but with for loop, it could finish repeating shapes in a second.
However, no matter whether people are drawing by hand or by computer, it requires inspiration and color choices. Only good aesthetic appreciation could lead to a good image.
The properties I used are basically sizes, coordinates, and color diameters. During the process of producing the image, the hardest thing is finding inspiration. Then I found that sometimes the shapes generated by the computer randomly do not look as good as designing every parameter by myself. So after trying to generate it randomly, I decided to write the code myself at last.
