What word is used to describe dancing with a trembling voice?

1, a person's dance, even if there is no audience, no applause, no praise, no envy of friends, I still have to appreciate my beauty alone.

2. Music has a melody that you can understand, and dance is a limb that you can't understand.

In the dim light of the strip, the heartbroken people dance with the wind.

4. Wearing shoes that don't fit you and dancing dances that don't suit you are like loving someone you don't love and doing something you don't like.

5, a person's dance, no audience applauds you, but it will also cheer for your own wonderful.
