I don't know when it started, or when the process began, but sometime last century, the first third perhaps, the output of classical music compositions just died. Classical music itself has evolved, of course, from Bach to Charles Ives, and I know there are *some* composers left (e.g. Philip Glass) but what happened? We gather here to discuss piano, but it's as if our love for music is ensconced in a time capsule and we're always looking back to an age where this music flourished. Is there a reason? Am I just unaware of masterpieces composed since the 1940s? Perhaps American culture coming into its own in the 20th century eroded the desire for classical music, exporting rock to the world, and capturing the cultural demand for it.
I would love to see a resurgence of classical music. I am interested in your thoughts.
First of all consider that the term "classical music" means nothing.
Music is music and the difference between the music created in a garage by a band and created in an accademy by a composer is just contextual.
So maybe you're talking about melodic music or instrumental melodic music or form-music (sonata, rondo, fantasia, concerto ...) or tone poem or symphonic incidental music.
That being said it's very flawed and simplistic to claim that people listen to varied genre of music because they're ignorant and stupid and that if they were smart they would listen accademic music. In fact it's very flawed to claim that accademic music is in any way a better or higher music.
No serious musicologist underestimates the huge important of popular music in the 900.
The evolution of our society and its political aspects is way more tied to popular music than to anything accademists have produced. There are big tomes in dozen of volumes just to analyze the importance of black music, of dancing music of the 40's, of country and the social ballads of the war time.
Another important aspect of music is that music has always and will always be an aggregative and social mean. Music exists as a way to tie people together and even for example the tradition of christian music is based on creating aggregation in like-minded religious people.
Add to that that music doesn't really evolve.
The difference in genres and styles is not like the difference between latin and italian, where italian is the evolution of an oudated latin, but more like the difference between animation and comics where the creation of animation stands on its own as "one of many" artistic means and not as an evolution of comics making them absolete and old.
The famous philosopher Carl Popper has written many treatises about the flaws in our understanding of time. What he stated is that in sociality and its products (like music, art, morality, laws, politics) there's no evolutionary straight line going from less evolved to more evolved but a circumstantial spectrum of contexts existing on their own and cycling.
That's is: history doesn't follow any kind of evolution.
In music this is even more straightforward since we're not dealing with standards changing and making old stardards absolete, but we're dealing with "tools" to communicate with this emotional and unintellectual mean called music.
So music doesn't proceed by stilistic novelty but by social contexts and individual creativity.
So you have a composer who has a predisposition for expressing emotions and ideas through the musical mean, which looks in this "box of tolls"and with those create what he/she feels creating which is clearly likely to be subconciously influenced by the social context in which he/she lives.
No honest composer composes with the goal of "creating new musical standards" or "advancing the theories of harmony". Those are nothing but collateral consequences which the compose himself/herself doesn't deal with and they're are not NECESSARY at all to create beautiful music that impact the lives of many people. No, a composer goal is to release his/her creative tension by "speaking through music".
So from this you can see that the kind of music you're talking about depends more on the social and cultural context and not on the theorical timeline. Because the truth is that the work of the theorist is not what makes music just like the knife is not what makes the dish.
Music resides somewhere else in the intention, spirit and emotive and creative core of the musician, the means of music (notes, parallel seventh, harmony, rests, poliphony, minimalism, chords, progressions, modulation ...) are nothing but cold impersonal timeless tools.
Talking about the social context you need to analyze the 900 well to understand what happened to music. Consider the depression years, where whatever person picking up veggies from an orchard had a task way more important that whatever accademist and when accademism was the prerogative of the wealthy, you can see how created a fracture between the ivory tower world of accademies and the real world of people.
Since the places of aggregation changed (from the theater, halls, cameras to the squares, fairs, dancing hall and political stands) the music that could be performed in those setting changed too. The living conditions changed and people were less likely to live in houses with pianos. The renting and flats economy changed more portable instruments became the norm for the cultural music of the 50's. Then came the black music, a strong life affirming music created by a group of discriminated people who nonetheless used music as a way to transmit hope rather than a way to ruminate about the negative aspect of the world.
People also were slowly breaking free from a tradition of norms and etiquettes whose only meaning was creating power division and were trying to get in touch again with a more instinctive side of their being. So all the dancing, rioting and simple music found a very good fertile terrain for this.
There's way more to this but you have to realize that not much changed.
Music (and popular music too) has been dealing with the social and cultural context in the same way that Debussy or Beethoven did. Many composers would be dealing with popular music if they were alive, because they knew that what matters is what YOU have to say, not what way you use to say it. Those composers chose the way according to the context they lived in, often looking for the most prolific one which is what they would nowadays.
Think about the difference between living in a world without radios versus a world with radios, think about the difference between living in a world where the social struggles between the very rich that can listen to music and the very poor who hardly have enough bread to keep their children alive versus a world were even the lower classes can afford lps, cds, tapes, think about the difference between a living in a world were citizens still lack the right to influence the politics versus a world were politicians are like social workers hired by every citizens, think about the difference between a world were not many can afford the teather versus a world were tickects for concerts are affordable, think about the difference between a world which has been free from the huge social rioting of black people emancipation, women emancipation, students emancipation, anti-war rebellion and a world after all of this has happed, this about the difference between a world where music can'tbe easily recorded and distributed versus a world where everyone can listen to the same piece over and over, think about a world where the teather is the most comfortable way to play live music and where outdoor performance were rare and and hard to organize versus a word were the portability of music has increased massively ...
... and so on. We have also to realize that many things we have been doing in classical time doesn't depend on will but on necessity. For example certain writing forms were created to accomodate the lack of mass printing of nowadays. If Mozart were alive nowadays he would have used radios, midi, synths, music-notation software, concerts and what not.
The bottom line is that we're accumulated tools that we can use to better express through music what we feel and have to say. We have also developed means of distribution that allows someone in Finland to easily get the CDs of a small group of local singers of Tanzania.
Now it's just time to stop focusing on form, theory, harmony, musical evolution that doesn't exist by its very nature and just make music in the most total freedom we have ever had knowing that it's easy nowadays to reach the people that would appreciate what we have the say with our music and that all music with an honest creative intention behind it needs to be respected and that there's no objective criteria for what is better or worse for what is more worthy to be listened and what not. We need way less pretentious accademism and technicalism nowadays (a moment in time in which we're turning into predictable robots and alienating ourselves from other people and genuine humna contacts) and way more genuine human humble creative crafts which can genuinely make people laugh, cry, think and doubt ... even if just for a night.
