Okay, maybe we need a sample of what a turntablist does:
Now if you pay attention to the actual process and the structural component, what you see is a sequencing, layering, rejigging/rearranging of elements to present new patterns and a unique presentation. He uses elements that in themselves aren't necessarily related. He may choose to make connections, or he may not.
Next, let's look at an example of what a practitioner of the pop art movement does:
Andy Warhol, Campbell's Tomato Juice Box, 1964, Synthetic polymer paint and
silkscreen ink on wood, 10 inches × 19 inches × 9½ inches (25.4 × 48.3 × 24.1 cm)
What we have here are two examples of the reproduction of previously existing elements to create something new.
I guess some of you fall into the semantic game. It's a musician if it plays a musical instrument. It's a musical instrument if it produces musical sounds. It's music if it produces sound with beauty of form, harmony, and expression of emotion.... And we can go on.
So the guy in the above video: is he producing sound with beauty of form, harmony, and expression of emotion on a tool that produces sounds?
Is Warhol producing art or is he just copying stuff?
Is a singer just making words sound pretty or are they making them into music?
Where do you draw the line?
