Just perusing Mark's What Every Pianist... again. Page 9 he does agree with me - 'We need to attend to movement throughout our bodies as we play the piano. We need to be aware of our bodies as unified wholes. That is because parts of the body that are not included in our awareness are likely to become fixed.[his italics]....We play a passage and notice a hint of tension building in our neck, so we release it.' No doubt that comes from the Conables I'm waiting for that to arrive.
