Singers who vary from pitch even to a small degree, are unable to sing with full beauty and easy production. The pitch must be centered. If physically, we are capable of singing any tone, we can sing on pitch. However, we must be sure that the sound we sing is thought correctly on pitch. The "Ear Training" program is designed to train the singer to "think" the correct pitch then sing the correct pitch and in doing so will develop a more beautiful tone. Actually all musicians regardless of the instrument will benefit greatly from learning to duplicate correct tones.
