I would like to make a clarification regarding the term avant-garde, which has one meaning semantically, but in the musical environment it is generally a term used to refer to music from a certain historical period that is now outdated. Current (contemporary) music is light-years away from that aesthetic.
To be clear, there is also the Latin term “nova”, combined with the word art and expressed in Latin as “ars nova,” which identifies the music of the 14th century and certainly not "new art" in a semantic sense... meaning new and therefore from today.
In general, we must distinguish between conservatives and conservatories in relation to where music is truly going.
That being said, the legendary DrJellyFish asks for enlightenment on the criteria for evaluating contemporary music... which is neither dodecaphony, nor serialism, nor structuralism, nor minimalism.
Let's return to the technological discussion, to the relationship of technology with everyday life, to the various cultural evolutions... let's retrace the history of the last century.
2 world wars (never before existed), Auschwitz, electricity, psychoanalysis, etc., have led to the maturation of different aesthetics that have mutated more and more progressively and frenetically.
Today I think that those who have most carried tradition forward, constantly renewing and codifying it, are precisely the jazz musicians.
But it must also be said that by now, and it has been this way for a while, that we are in the "third practice"; one cannot pretend that electronic music does not exist, so it is an area that I urge you to cultivate.
But not because it is a duty, because you hear it everywhere now... today there are not only problems related to language, and I think a musician today must understand and know about it.
