The most important melody in a piece of music is called the theme. The theme of a piece makes up the principal melodic material. Theme is a general term for the basic subject matter in a piece of music. Fast pieces have short themes.
When a composer chooses to compose a piece using a particular form, this helps him/her organize the music so listeners can have a good balance of music they recognize mixed with music they haven't heard before. Rondo form is a piece of music where the musical material stated at the beginning of the piece keeps returning. This opening music can be called either the theme or the refrain; they are the same thing.
