Of the curved line it has been said in ancient India that it achieves the condition of Music. So it has often been called the singing line. Certainly, it is the line, evocative of those harmonious movements of the nerve ends of the hand which ally the body-soul with lovable round shapes. In this sense the creative curvacious line is the opposite of the straight line, direct, hard and clear like the sword of pure knowledge. While the curvacious line transforms the lyrical feelings and presents a coherent experience, the straight line discriminates between one experience and another.
