Looping is pretty much the foundational cornerstone of hip hop.
Breakbeats.
Hip hop isn't rocket science. The genius lies in the simplicity.
Then you had brehs who came through later and really advanced sampling. :havdahell:
There's no difference between playing a guitar and looping a guitar. A guitar only produces but so many sounds. Classic rock songs aren't premised on how technically complex the guitar playing is. (I'm out of my wheelhouse here but that's my understanding). It's all about arrangement. That's what Sampling is.
I think that doesn't really apply once you get to the 70's
or even the late 60's effects pedals were coming into
play which altered the timbral aspects of the guitar
all of a sudden you have fuzz, wah, distortion etc.
That's without the natural variation an actual instrument
has vs a sample or the harmonic and melodic possibilities
that come into play once you look at the major scale, it's modes
and the dozens of exotic scales that exist separately from that.
The guitar with its 2 and a half octaves is quite the versatile instrument, alone it can fill several roles especially once looping
is involved. It's quite different from looping someone else's
guitar playing, especially if you don't have to come up with the
chord progression yourself.
Things get considerably more complex when you have to consider
other aspects of song writing like arranging strings or horns yourself vs simply sampling them. There are things real Instruments can do that a sample never can much like there are things a sample can do which are physically impossible.
But yeah, original music can be inspired by sampling.
There are things that Robert Glasper does that are directly
inspired by the looping of piano chords by Dilla or that his
drummer does that are directly inspired by Pete Rock and so
on.
I don't think sampling is useless but I do think it's importance is being
overstated. We're at a point that I personally think sampling should
be used with original works (it's been done and it works !)
That way you get the best of both worlds.
No royalties and the unique aesthetic that comes from
sampled music.
