I just suggest this because this was similar to how I started liking
classical music while growing up. I didn't come from like a conessieur
(sorry for my spelling) family or anything, so my exposure was very
limited. (My dad's a plumber and my mom was like a clerk at JCPenny's
or something at the time) Believe it or not I got inspired to play the
piano from a Bugs Bunny cartoon "Rhapsody Rabbit" playing Liszt's
ever-popular Hungarian Rhapsody #2. So my grandparents bought me a cheap
little spinet piano and some lessons by a grad. student, and I've had
fun with it since. However, one of my personal favorite pieces "Waldstein"
has great emotion and development while pertaining that immediate
Increasing boredom like you mentioned is a big concern, (that's part
of the reason I'm a theory/comp. major instead a piano performance).
I discovered my way through this boredom by learning to appreciate
"new experiences and realizations" I find in certain avant gardes and
neo-classism pieces. (Others I find as trash, but each to its own, lol)
Some of the in-depth Romantacism/Classical pieces people love didn't
quite strike me the same way as some modern pieces do. One thing I
noticed about composers these days is the music they write tends to be
in correlation to their personalities. I can usually expect something
great from some one with an intelligent out-landish personality, and
contrasting with this I can expect something as a painful experience
from a "nerd" composer whose intelligent with no personality who should
be strictly focused on anayltical and not compositional techniques.
Anyway, I went tangent, but the point is, there are many ways to push
forward once introduced. Do you really think they can go back to hip-hop
once heard some of classical's most impressive and virtuotic "greats"?
Just food for thought,
