Italian form for English caper

Caper means a playful leap such as you see someone doing it in a ballet.
I'd like to find an Italian word (adjective, or contiuous tense form) for such a playful act.

As a matter of fact I failed to find it in an automatic translation program.

Dear Raphillon,

The following 4 sets of Italian words are meant to describe 4 different pieces of music. Do they mean anything to you? They should be used to describe the artistic impression left on the audience or the artistic effect produced by the pieces of music.

1. Allegramente, ispirazione, and tempo in Marcia.
2. Primordiale, semplice, and sincero
3. Burlesco, piroetta, inspirato, and comico
4. Delicatamente, ampio, variopinto, and pomposo

Dear Raphillon,
When I say Delicatamente, or delicato, I mean the theme of music is very finely treated in every detail. I am no musician, probably I cannot explain it in a way that even non music people can readily understand.
But I am very satisfied that you responded with a standard Italian text.
Many many thanks.

Dear Raphillon,

This Chinese orchestra performance titled Song of Science Capriccio Suite is as a matter of fact a medley of 7 series of music and songs with different themes, and the title for number 7 is used as the title of the whole work.

I'd like to know your opinion of the general title for the whole work.
