What is perfection in music?

For some, it might be unity; for others, it might be execution without false notes or perfectly polished aesthetic plasticity.
First and foremost, the source of music is spirit. It is born from internal sources such as emotions, psychic energies, perfect theoretical knowledge, and intelligence. In other words, it is not held back by any physical contingency. At this stage, music is ‘perfect’ in its essence and is not held back by material conditions. However, its true birth and manifestation are through sound: the vibration of a body in the air.
Would perfecting it mean transcending matter and rendering hearing without pitfalls so that music returns to its natural state of pure spirit?
