I'm using shorthand for "intrinsic properties". What are intrinsic properties to music if not the way it sounds?
"Sound is an audible mechanical wave propagating through matter, or the perception of such waves by the brain."
Sound can be understand as music in a moment. This misses the temporal change within music, the horizontal structure.
Er...no...but noone is arguing that Techno might be CM. You wanted to rule out electric instruments. I pointed out a case where this rule would fall. Doubtless there are others that would also fail. You can't make up a rule and then start making exceptions one at a time.
I gave various possible definition of classical music.
Definition by derivation from classical institutions: A work for classical orchestra is still a work for classical orchestra when you include one non-classical instrument. So one non-classical instrument does not change the overall classical charcteristic. But if you substitute everything with electronic instruments it would not be a work for classical orchestra anymore.
Definition by 2 out of 3 criteria. When I said that music must fullfill 2 out of 3 criteria to be classical and one of them was non-electronic sound generation, this means that non-electric sound generation is no problem as long as the other two criteria are fullfilled.
Open definition: If it is not Techno or another specific form of Popular music, than it is Art music.
You could also just count the portion of electronic instruments. If 5% are electric, then 95% are non-electric. You could say it is 95% classical.
But what aesthetics? Get specific, please.
Medival, Renaissance, Baroque, Classical, Romantic, Modern, Opera, Orchestral, Chamber, Lied, Chruch, Ballett, Solist, Film etc.
Again this doesn't work. Alkan wrote a Symphony for Piano. So did others.
That is a symphony just by the name or idea but not a real symphony. I posted earlier the pop song Little Annie Rooney. It also has a 10 second section called "symphony":
This is a symphony in a different sense, and not a symphony in the sense of Beethoven.
