No, what I described is based on rules of human perception, which encompasses all people....What you are describing is ’taste’.
I thought when people used the term "musical" it was to make a value judgment about the sound being produced by the amplifier (and speakers), not state a fact which would apply to all perception.
Here’s how I see it.
Some people eat hot peppers and call them spicy. Others say they’re mild. Does chemistry tell us who’s right? Hardly.
Peppers do have a chemical component, Capsicum, that causes them to interact with taste buds and then the brain.
But what can one claim as "objectively true" about this sequence? Some people need only a small amount of capiscum to cause them to call the food "spicy." Others need a lot. Who is right here? The chemical explanation cannot sort it out, because perception always comes to us as interpreted, never raw.
The same situation exists, pari passu, to "musicality." Some people’s taste will hear certain harmonics as pleasing; some not. It depends on taste, preference, circumstance, habituation. No way to disentangle it.
Clearly, you and others have discovered there is a widespread predilection for 2nd and 3rd order harmonics, and there is a predilection for sugar, fat, and salt, too. But all of those preferences could be changed by changes in taste -- and the underlying physics would have no impact at all.
