Back again.
I would like to discuss a few points, cued by some things that were said here.
First of all, does somebody's expression in literature, music, painting, architecture, etc. qualify as high art, merely from the effect it has on the eye or ear of the beholder? Not really... It can qualify as a preference of the beholder (intimating his tastes), but not as a consensus. Now, what if a devastating number of people subjected to that somebody's expression, world wide, agreed that it indeed qualified as a product of high art? Again, not enough. One would have to review what other works these people also consider as high art. If Bieber is mentioned...
Can we make an, as objective as possible, pronouncement regarding this 'so-called' Epic school, as an artistically valid type of orchestral composition? We certainly can:
This type of orchestral composition is exclusively utilised as background scoring for film and video games. There is no way that any orchestra of any note will perform such a work, unless it already exists as a score to something... No one will ever commission orchestral music of this type for its own sake (for a symphony, concerto, opera, ballet, you name it), and I don't know of any 'serious' composer that belongs to this "school" of orchestral writing. Conversely, I know of 'Minimalists', 'Spectralists', 'Neo-romantics', 'Free-atonalists', etc. Enough said. This kind of "music" is dim, and its composeurs are a joke outside of Hollywood, BBC, and Playstation.
Let's now eliminate all other types of orchestral composition and concentrate exclusively on media music and why, Hollywood for example, propagates this kind of symphonic refuse. Is it,
a) Because people like it? Not necessarily. People did not have any problems with the likes of Williams, Shore, Barry, Goldsmith, etc. before this kind of orchestral bile rose inside Hollywood's oesophagus. People are mostly there for the movie. They'll like pretty much anything although, other than Hans, I haven't seen much veneration for any other such composter, comparable to that which say Morricone enjoyed,
b) Because this kind of score suits a particular kind of movie (or game)? Again, no. This monotonous, lobotomous, layered crap has been employed in most genres: Action, Thriller, Suspense, Adventure, etc. I refer everybody to the aforementioned names. They scored such films a lot better, a lot deeper - with real layers,
c) Is it because this kind of music costs less to produce, so in effect it is the product of financial considerations? I am not an expert, but I don't see how this kind of orchestral claptrap is cheaper to record with an orchestra than any other score; and if it is, I have never read it from anyone in recently published books, or relevant YouTube interviews.
So what's the reason for this music's use then, if it's absolute crap and no cheaper than a proper score?
I won't go into that, but I'll just say that music is not the only aspect of film making that has gone down the public toilet. Compare the Star Wars of the '70s to today's as an example. Compare re-makes, etc.
Anand mentioned Jim Morrison. Who is the last 30 years' Jim Morrison, Paul McCartney, Billy Joel, Roger Waters, Benny Andersson, Freddie Mercury, Elton John, Phil Collins, Jeff Lynne, Barry Gibb, Roger Hodgson, Mark Knopfler, Eric Woolfson, name your own... Anybody comes even near?
Back to the software. fatis12_24918 said the pyramid is based on rhythm, then timbral colours, then melody, then harmony and finally counterpoint. This only applies of course to this Trailer park "music" this software facilitates. Music, in the western world at least (and orchestral music was born there), began with melody/rhythm (we'll never know which came first), then counterpoint, then harmony, and finally timbre. And it was always sophisticated; as sophisticated as it could be at any time.
Finally, the orchestra is an instrument in itself. It has developed from the chamber ensembles of the past, to the Classical orchestra, then the Romantics added size and instruments, and so did the Modernists in the 20th century. Its constituent instruments have developed and changed over time from their original forms, much like the development of the piano.
How one composes for this 'instrument' does not depend on the 'instrument'. It is capable of Mozart's 40th, as it is of Lutoslawski's 3rd. Capable of Captain Blood, as it is of Superman (1978). Sadly, it is also capable of Man of Steel (2013).
The instrument does not make you a composer - any instrument. It will however reflect the composer you are, according to how you write for it. And remember: Technique is not a matter of taste, or opinion.
