Teenagers, especially those with uneducated ears, don’t like classical music, and they think it’s not “cool” to be seen by their peers listening to it.
Still other explanations are in the nature of classical music itself. Much of it conveys a sense of order, symmetry and beauty, that conflicts with the disorder and ugliness in the minds of hooligans.
Musicologist Giovanni Bietti explains that Beethoven — who was convinced that music could make a great social contribution — Mozart and Haydn had a rational image of music, which is why in their works the initial contrasts are always resolved through the rules of composition, giving order to thoughts. This discourages those who don’t accept the rules.
It’s like the link between criminal behavior and rap, through the rap lyrics and the “music” — or rather cacophony — itself.
I think it has more to do with the heavy, simple bass rhythms that are a feature of modern music. Think: pounding on a log with a club….
BTW, there’s a reason that among the young, Asians dominate classical music performers. Ask any local piano teacher.
