Bear in mind that parts of the score may be devoid of direct musical relevance.

The notation is more important than the sound. Not the exactitude and success with which a notation notates a sound; but the musicalness of the notation in its notating.

The score must govern the music. It must have authority, and not merely be an arbitrary jumping-off point for improvisation.

Bear in mind that parts of the score may be devoid of direct musical relevance.

A Composer who hears sounds will try to find a notation for sounds. One who has ideas will find one that expresses his ideas, leaving their interpretation free, in confidence that his ideas have been accurately and concisely notated.
