Jiddu Krishnamurti sums up perfectly the artist vs. the technician:
You cannot reconcile creativeness with technical achievement. You may be perfect in playing the piano, and not be creative; you may play the piano most brilliantly, and not be a musician. You may be able to handle color, to put paint on canvas most cleverly, and not be a creative painter… We have technique…how to put up a house, how to build a bridge…how to educate our children through a system…we have learned all these techniques, but our hearts and minds are empty... Creativeness is not found through technique. If you have something to say, you create your own style; but when you have nothing to say, even if you have a beautiful style, what you write is only the traditional routine, a repetition in new words of the same old thing… So, having lost the song, we pursue the singer. We learn from the singer the technique of song, but there is no song; and I say the song is essential, the joy of singing is essential. When the joy is there, the technique can be built up from nothing; you will invent your own technique, you won't have to study elocution or style. When you have, you see, and the very seeing of beauty is an art.
