Music theory is the necessary instrument you have in order to understand and explain the beauty of musical artworks in musical terms. People who do an apologetics against music theory are not humble enough to pay reverence to the great musical artworks trying to understand them.
It is like believing that your ear hears better when it doesn’t know where to go. Your ear brings many perceptions, but only concepts will create an unified meaning out of these perceptions.
Fun fact: the same people start to theorise “their” theory.
😂
If your theory doesn’t pretend to describe reality based on the efforts of previous theories and solid methods respected by those who created the culture in which you are born you are very likely to look like a fool.
Music theory is not enough, but neglecting it is a sign of negligence against the fundamental curiosity to understand how musical beauty in the most objective categories works.
So, if you love music, why do you hate the conditions to properly understand it?
