London neurologist Barry Wyke maintains that immediately after a note is initiated, its continuation is taken over by that part of the brain responsible for reflexive action. What does that imply? Can we practice only the incipit? Yes, and to great effect. Take an entire vocal phrase and sing both words and pitches at half voice and well articulated, each note as briefly as possible, barely touching it, short. Very short. Sing each with the mental energy, though not the amplitude, of your full voice. Stop. Wait. Come back to your full voice and let each note continue itself. Note what has occurred. This can be miraculous.
