Is musicality contingent on good technique?

In the Webster's dictionary a pianist is used to illustrate the meaning of the word "technique". Interestesting. I guess even they know that beautiful expression is impossible without good technique. Technique helps control, modify, and free the many body movements crucial to fine pianism (Lois Nielson, Clavier Companion Sept./Oct. 2010). If all the parts of the body are well-positioned and controlled, movement is free, extensions are easy, voicing is distinct, and musical lines and colour are possible.
