"The central factor is imagination; what can be done without it! Can you
think of a musician, especially a singer, without imagination? He may
acquire the letter--that is, execute the notes correctly, but the
performance is dead, without life or soul. With imagination he
comprehends what is the inner meaning of the text, the scene; also what
the composer had in mind when he wrote. Then he learns to express these
emotions in his own voice and action, through the imaginative power,
which will color his tones, influence his action, render his portrayal
instinct with life. Imagination in some form is generally inherent in
all of us. If it lies dormant, it can be cultivated and brought to bear
upon the singer's work. This is absolutely essential.
