A Musical Exercise
The child should be taught to recognize tones, and the spaces between tones of the scale. Have him stand with his back to the piano and learn to tell the difference in the tones that are played. First, use the octave, then the one-five-eight. Next the one-three-five eight; then the one-two three, etc. Then introduce the half-tones. This exercise can be made more difficult according to age and musical ability.
