Bridge (music)
（重定向自Bridge passage）
In music, especially western popular music, a bridge is a contrasting section that prepares for the return of the original material section. The bridge may be the third eight-bar phrase in a thirty-two-bar form (the B in AABA), or may be used more loosely in verse-chorus form, or, in a compound AABA form, used as a contrast to a full AABA section.
