The purpose of this paper is to show the most convenient system of notation of continuous gradual change of pitch (CGC) within the possibilities of our present five-line staff of musical notation. Fig. I shows the three most characteristic types of CGC:
Type A: The increase of pitch per unit of time is constant.
Type B: The increase of pitch per unit of time increases.
Type C: The increase of pitch per unit of time decreases.
Of these, type A appears to be less frequently used than the other two.
