But why is it that sometimes improvised music can be just as good or even better than the music you have sweated over and thought lots about?
The key word here is a word that is, unfortunately seldom used, which, if it were, would possibly cause people to see that there is usually more ways to skin a cat than is generally presented. That word is "sometimes".
If you follow the logic of what Lt Bob was saying, then it stands to reason that
sometimes, improvised music will be better. I've witnessed this {heck, sometimes I've been involved in the playing of it ! } many, many times.
It also stands to reason, by the same logic, that
sometimes the music produced won't be better. It
might be dull. It
might be average. It
might be uninspired.
Most of what happens in the brain is unconscious, and possibly because it is free from the interference of conscious "agendas" it can proceed rapidly and efficiently, following innate and maybe instinctive laws of musical theory, to produce something of value, without any consciouss effort being expended at all.
That may or may not be true. I don't think the brain is like that. Alot of information, learning, consolidation, processing and reinforcing goes into and on in our minds on a daily basis over a lifetime and comes out in different ways, some of which may not be 'conscious' as you put it. But even if your quote were entirely the case {and some bits of it, I do accept}, the more 'instinctive' creation wouldn't be guaranteed to be any 'better' than a thought out creation than would a trip to the beach that you thought of there and then and acted upon as opposed to one you'd been planning for a week.
Fact is there's many, many ways of approaching it because it IS all in the mind and different minds work differently.
There are many examples of excellent music done in all the ways mentioned so far and countless others that haven't been.
I often look at the explosion of pop and rock bands in the UK and USA during the 60s as being unique in the sense that you had this coming together of so many different types within any one band. Look for example at the Who. You had Roger Daltrey, the tough working class "I'll talk with my fists" sheet metal worker, Pete Townshend, the slightly disturbed arty farty guitarist from the dysfunctional family whose parents were theatrical/musical, John Entwistle, the French horn playing theorist who loved rock but found it to be too simplistic for his abilities and Keith Moon, the anarchic Peter Pan for whom order seemed to be anathema. Each one had a completely individual and different approach to making music.......but ended up in the same band. Their's is a story that could be replicated hundreds if not thousands of times but shows how different people with different approaches and mindsets can be equally valid within the same situation.
historically you can find tons of examples all over the place as far as how much they planned things out or just let the spirit guide them.
Both methods have resulted in transcendent music.
We were mentioning in a David Gilmour thread the other day how we both dug the Monkees and the Mahavishnu orchestra. Both seemingly the antithesis of one another, even within the Monkees there is sometimes a great improvisational thread while sometimes, the Orchestra were very 'composed'. But generally speaking, the Monkees stuff is well crafted while the Orchestra improvised alot {the original orchestra fell out and broke up partly because of that - Jerry Goodman and Jan Hammer felt that what they brought to the improvisational passages should have netted them composer credits. John McLaughlin thought otherwise} but both bands made utterly beautiful music. And some of it truly transcendent.
For example, since in this conversation carefully plotted music is being said to result in tripe, what about classical music, virtually all of which is carefully thought about and planned and plotted? Very little imrpovisational aspects in any of it except some of the avant garde stuff. Certainbly there's very much beautiful spiritual music conceived that way.
I was thinking of classical music when Timtimtim first made the point he did about great music making itself. I reckon Brahms, DeBussy and all those other Schuberty, Mozarty composers of yesteryear would bust our noses if we said that to them, especially given that many of their pieces were commissioned by royalty in the days when the wrong word from a prince could have you clapped in irons, sharing your cell with hungry, undiscriminating rats.
but to make blanket statements about what method makes good music and what doesn't is simply a way to definitely be wrong.
In a nutshell.
