Who says music has to be melodical and repetitive?

When all the noise goes harmonious, I think I realize what music communication is, what a real band will do. Each member of the team was maintaining the sound of the little device by their developed unique skills via experimental recording process. When nobody practice the performing before, as long as the sound was playing, they eventually fit in together with rich layers, each level of frequency can be differentiated as bass, mid and treble. It is not as significant difference of traditional music as the noise we imagine initially. I wouldn't even call it as noise, because it just hit the opposite way of traditional music, which feathers non-repetitive, unpredictable, sometimes even uncomfortable sound. I was clicking when my other mates went silence, because it sounds like a complete piece. It was found when my group was recording in the baby changing room, I took the mug with me. What will it sounds like when I swing around my copper disk in the mug? As a lot people doing the same device. How can I make my own skilled, reproducible sound instead of making random sound? That is the way I made my own device as instrument.
This kind of random but reproducible sound can extremely enrich the effect of DJ or other live musician. As they playing with the device, with switched or buttons which can change the value of resistors, the sound can be recorded as sampler while they can be added onto industrial music, even achieve a revolutionary new genre of music.
