TAGORE: Instruments are used, not for harmony, but for keeping time and adding to the volume and depth. Has melody suffered in your music by the imposition of harmony? EINSTEIN: Sometimes it does suffer very much. Sometimes the harmony swallows up the melody altogether. TAGORE: Melody and harmony are like lines and colors in pictures. A simple linear picture may be completely beautiful; the introduction of color may make it vague and insignificant. Yet color may, by combination with lines, create great pictures, so long as it does not smother and destroy their value. EINSTEIN: It is a beautiful comparison; line is also much older than color. It seems that your melody is much richer in structure than ours. Japanese music also seems to be so.
