大概在音乐史上，最为级进的旋律，是我们第一堂课上撇过一眼的，贝多芬的《欢乐颂》。

And possibly the most conjunct of all melodies in the history of music was the melody that we looked at very briefly in the first gathering, and that is Beethoven's famous Ode to Joy.

舞蹈是脉搏，是心跳，是呼吸，是生命的旋律。舞蹈是时间，是运动，是幸福，是欢乐，是悲伤和嫉妒的一种表达。

Dance is your pulse, your heartbeat, your breathing. It's the rhythm of your life. It's the expression in time and movement, in happiness, joy, sadness and envy.
