A potter may imagine the soft lines and symmetry of a vase, yet if she cannot control the clay on the wheel there will be nothing but a gray mass of sludge. If a writer imagines his story in the deep recesses of his mind, yet does not know grammar and vocabulary, if he cannot master the weaving of words into a coherent and dramatic structure, then there is no novel.
People have told me that I have a nice voice, yet I am untrained and no matter how much I enjoy belting out a song, I know I will never, ever be able stand up before an audience and perform without making a fool of myself. I have not mastered the craft of song.
Similarly, I have been exploring music through drumming, but I am a novice who can’t even read music. Yet, I move forward through study and practice so that I may, hopefully, someday master my craft and be able to artfully conjure the emotion that drumming can evoke.
Whatever your medium or genre, practice your craft until it becomes art.
