A statement like this really represents your lack of knowledge concerning music pre-1850. Mozart, Haydn, Bach, Handel, Machaut, Palestrina, Dittersdorf, and many others felt that creativity and originality was important in art. Yes, they built on foundations - much as we do today - but you can clearly hear differences when listening to each. Take Vivaldi and Handel, for example, you can't really say there are no differentiating characteristics between the two. The same is true for Beethoven and Mozart. Haydn and Schubert. Mendelssohn and Schumann. Wagner and Verdi. Schoenberg and Webern. Xenakis and Ligeti. I could go on. I think the historical record of music clearly reflects that creativity and originality have ALWAYS BEEN a defining force, so much of the idea that this force is NOT universally valid.
The three points I gleamed, highlighted above, are:
1. The overemphasis of innovation, revolutionizing, and lack of emphasis on craft has lead to a crisis and erosion of Western Aesthetic Ideals.
2. Why write music that is so new and exciting that it can be accessible or enjoyed by an elite few, i.e. serialism or 'chance' music?
3. The challenge to art today is to use and carefully transform the old traditions in order to express things that are relevant to us today - as in the vein of Arvo Part and John Tavener.
Ok, to address these three points:
1. So, your saying that we overemphasize innovation in music. The more innovative and original the work, the better the composer. The history of Western Classical Music has, for the past 1000 years, been built on a tradition of musical expansionism. We see this from the simple monophony of early composers to the extreme polyphony of composers in the Renaissance to the contrapuntally rich fugues of Bach to the extremely complicated formalistic fugues of Mozart and Beethoven to the richly harmonic polyphonic works of later day composers - each have built upon innovation, revolutionization, and creativity/originality. In these composers lifetimes, ALL OF THEM, were faced with an audience that did not understand there works. We often look back at the works of these Masters as being widely accepted and listened to IN THERE TIME by everyone. The truth is, that was not the case. In the 1700s and 1800s, at most 95% of the population couldn't even afford to feed themselves - let alone attend a concert. Classical music, at this time, was the music of the aristocracy - and was attended by the aristocracy. Yes, as the Industrial Revolution rose there emerged a Middle Class. As the 19th Century faded into the 20th Century, the Middle Class was able to become 'cultured'. I would recommend, by the way, taking a class on Folk Music. I enjoyed the course - it really opened my eyes on the evolution of that often forgotten -on this forum- music of the 'common folk'. Bach, while we love him today, was NOT a composer wildly known amongst the largest class of people at that time, unless of course, you were lucky to be in the congregation of the church he was organist at.
2. Why should I write music that is inaccessible to a few (i.e. serialism or alleatoric music) Well, my answer to that is simple: because I can. I find that kind of music to be challenging on a number of fronts. For one, it is NOT easy to make either style of music well. With both types, you have a lot of factors you have to take into account. Avoidance of a key, or supremacy of one note over another, means you have to do other things to sustain interest. Many of these things are barely focused on in writing 'tonal' music (whatever that term may truly mean.) Not relying on a 'tried and true' progression means you have to overcome obstacles in different ways. This is no different, really, than the obstacles Bach created for himself in his fugues. Or the obstacles Mozart created for himself in his vocal writing. Or the obstacles Beethoven created for himself in the forms he adapted to fit his ideas.
3. I agree with the countless of composers who have come before me. The challenge of my art today is to build upon the old traditions and contribute to them with my own unique perspective. I don't just look at composition as an 'old tradition' that has to be adapted for relevancy today. I view music as being relevant regardless of whether it takes into account old traditions or not. It's an appendage of human culture. The whole of human culture does NOT transform old traditions. We, as a species, have continuously added new things to our cultural expression. Many of these new things have, many times, conflicted with old traditions. That is what being human is - constant change and adaptation. You can't have it both ways. That said, I think the challenge to composers today is not to transform old traditions to express things that are relevant but instead is to take the things that are relevant today and express them humanistically. I don't speak the language of my forefathers - nor do I dress/act/behave the way that they did. I'm sure you don't either. So why should I use their musical language?
