I remember watching George Bolet teach a Master class of piano and hearing him tell the extremely talent student who had just finished banging out a remarkable cadenza from Rachmaninoff...
"If every note, every phrase, every line of your performance is a "peak moment", then--in effect--you make it impossible for a peak moment to exist. You must begin down here, quietly and build your momentum and interest so that when something really important and dramatic is about to happen you HAVE SOME WAY OF COMMUNICATING IT."
It is worth thinking about.
