An artist in any field has equipment he uses to get his final product. Whether this is the painter’s brush, the photographer’s camera or the electronic components used by a mixer, the various aspects of his equipment must be understood well by the artist before he can easily communicate the message he has envisioned.
If one is trying to take a picture but doesn’t understand the workings of the camera, he can become so interiorized into the camera that he doesn’t put his attention in front of him on the picture he wants to take. A painter can get so interiorized into the working of his brush that he doesn’t see what he is putting down on the canvas.
The key to this situation is drilling. The artist should drill with all of his equipment until he feels confident with it and doesn’t have to put all of his attention on its operation. A good photographer won’t take a picture unless he is familiar enough with the camera that he can exteriorize from it. A mixer has to know his equipment well enough that he isn’t introverted into it or he won’t get anywhere.
Once the artist has fully drilled and gotten competent with his tools, his attention no longer has to be introverted into the equipment or what he is trying to do. He can then freely express himself, and he will find that he is getting much improved artistic products.
