I see someone who uses "phrases" similar to a collage artist. Sure there's a place for it and some people buy it, but I think Picasso, Van Gogh, DaVinci, Michelangelo, etc. would be rolling in their graves.
Picasso used pieces of things in some of his sculptures - tin cans, etc. The result couldn't have been anyone other than Picasso. You know it's him before you read the placard. And when Matisse couldn't move a brush anymore, he had his assistants cut up pieces of paper that he put together. Again, the result was obviously Matisse.
I agree with Mathis - it's the thought behind what you do that counts,since it determines the outcome! And I say that without trying to be pretentious. After all, the name of my publishing company is Derivative Music. [:D]
(Really! I was surprised it was still available.)
By the way, I've had this discussion about loops before, when someone compared using loops to Andy Warhol. I think that's a good analogy. What I said was that I like Warhol, but you get the idea pretty quickly and move on to the next thing in the museum. By comparison, one can stare at many of Picasso's paintings for a long, long time and keep seeing something different.
The part where the analogy breaks down is that there's nothing to prevent music that uses loops from being really interesting, as long as there's other stuff going on. What I don't like is when one loop is the whole thing. I'd been listening to Weather Report at the time we had that discussion, and I said that you're constantly going "ohh, ahh, ooh, wow" - and half the time what's going on is implied. Someone might come up with one bar like that (and when it's only one bar, nothing is implied), probably watered down, repeat it over and over, and that's their tune. Or maybe they'll put a pad on top or drop something out for two bars.
Anyway, I prefer to come up with my own 1-bar pattern and cut and paste if I'm trying to get that feel! It's just the way my brain works. Every time I've tried to start wtih a loop, I end up piling on stuff, and then it ends up sounding better without the loop anyway!
So much for saving time.
Sorry for getting carried away when we're talking about sampled phrases rather than loops, but I think it's the same idea.
