I must say that I am all the way on Ted’s side on this one.
Although I have a huge interest in musical theory, teach it and insist that my students do analyse their pieces (for a very specific reason that may be not quite what one would expect), and although I agree with many isolated statements by Daevren, his overall conclusion misses a very important point:
The history of music theory is the history of breaking the rules of music theory. One only need to look at Haydn criticising and trying to “improve” on Beethoven’s compositions (and Beethoven’s disgust at it) according to the “rules of theory”, to feel glad indeed that Beethoven didn’t give a toss.
Or Bach’s harmonisations of chorales – which to this day are studies by harmony students – that defy theoretical organisation.
Think about Scarlatti sonatas. Try as you might you will not be able to point one as “typical”. Scarlatti constantly surprises and breaks his own rules (or what we may perceive as “rules”). The fact, is that in many cases (if not in all) most superior composers are not following “rules” or “formulas” even when (e.g. Mozart) they appear to be doing so.
In composition, theory is always an after-thought, never a previous condition. The musical theory that models and explains Mozart’s music did not exist in Mozart’s time. In fact the first theoretical compilation was the treatise by Rameau in the early 1700’s. He figured out some important organisational issues like the fact that a C major triad was still a C major triad even if it was inverted. The marriage to physics would have to wait at least 150 years when Helmholtz published his (then) ground breaking work – most of which is still valid today – “On the sensations of tone”. Before Rameau, theory – if it existed at all – consisted mostly of “tricks of the trade” jealously guarded with secrecy by musician’s guilds. None of this stopped the composers of the time to come up with some of the most sublime music ever written.
Yes, - as Ted said – if you want to compose pieces in the style of a certain composer, the theory relating to that composer (incidentally there is no universal theory that applies to everyone – as there is no single way to analyse a piece of music – Schenkerian analysis is but one out of many possibilities, and many times it will be totally inadequate) will be very helpful, and you better stick to that particular set of rules, otherwise it will not be in “style”. But otherwise, theory can be a two edged tool that may help or hinder you in equal measure.
This is not to say that theory is useless – quite the opposite. For a total beginner, theory will be an enormous time-saving device. But eventually one has to master it and then let it go. I suspect Ted is in this case: he has a vast experience of these things, they have all been internalised at the unconscious level, he does not need it anymore.
If you think this subject in terms of language, grammar is very important, and yet, grammar does not come before language: it explains language, and as language changes through usage, so must grammar follow suit. One can easily imagine a narrow minded grammarian taking issue with Joyce’s “Finnegan Wake” or Mark Twain’s “Huckleberry Finn”.
Best wishes,
