《淮南子·兵略训》
所以鼓不参与也不产生五音，但它却是五音的主宰，水没有味道，但却能与五味调和，将军不直接参与五官的事务，但却是五官的总督。
故鼓不与于五音而为五音主，水不与于五味而为五味调，将军不与于五官之事而为五官督。
Therefore, the drum does not participate or produce the five kinds of sounds, but nevertheless it regulates the five sounds. Water has no taste, but nevertheless it can be combined with the five tastes. The general does not participate directly in the affairs of the five officers, but nevertheless he oversees the five officers.
