把这一句，留给此刻的你
The number of strokes to the inch controls the pitch of the note: the more, the higher the pitch; the fewer, the lower the pitch, the size of the stroke controls the loudness... the tone quality is the most difficult element to control, it is made by the shape of the strokes.
每英寸的笔画数控制音符的音高:笔画越多，音高越高;越少，音高越低，击球的大小控制着响度…音质是最难控制的因素，它是由笔画的形状决定的。
