浩瀚无垠的宇宙充满了节奏,大自然岁岁年年的重复,春花秋月的交替,日月星辰的出没,大海潮汐的涨落,人体心脏的跳跃,脉搏的起伏,时钟的摆动,汽笛的嘶鸣……可见节奏是事物运动中某些特征重复出现的规律。《乐记·疏》:“节奏,谓:或作或止,作则奏之,止则节之。” The vast expanse of the universe is full of rhythms, the repetition of nature’s years of age, the alternation of the spring flowers and the moon, the sun and the moon, the tidal fluctuations of the sea, the jumping of the human heart, the fluctuation of the pulse, the swinging of the clock, ...... It can be seen that the rhythm is the law of repetition of certain features in the movement of things. “Music note sparse”: “rhythm, that: or make or stop, then play it, only the festival section.”
