The rules are like the notes on the page, and that gets you started, but then you dance around the notes on the page, coming up with just the right combination for this particular moment with this particular set of fellow players.
规章制度就像纸上的音符， 你先按照音符所定的曲调开始， 但是然后你便在音符之间即兴发挥， 与当时那些一起表演的人一起 跳出那些最符合当时那个时刻的 最美妙的最佳配合。
