Is there a word for the opening of a song?

I'm looking for a word (if such exists) for the opening of a song.

Specifically, the part before the singer starts singing the lyrics, often a 30 seconds to 1 minute solo instrumental at the beginning of the song. Like how the word kick-off, is used for conversation.

Does such a word exist?

Answer

Just to expand on Josh's answer: the term introduction is mostly used in the shortened form: intro, especially when it comes to contemporary music.
