诙谐曲（Scherzo），是一种快速，节奏强烈的器乐曲，一般为三拍子，有令人惊奇、幽默的特点，是从小步舞曲中发展出来的，原文是意大利文意思是“玩笑”。

海顿首先在写作奏鸣曲时用诙谐曲代替其中的小步舞曲，后来贝多芬、舒伯特都运用这种手法。肖邦更是写作独立的钢琴诙谐曲，更具有戏剧性。

也有作曲家用这种手法写作声乐作品。

A scherzo (/ˈskɛrt.soʊ/; Italian pronunciation: [ˈskertso]; plural scherzos or scherzi), in western classical music, is a piece of music, often a movement from a larger piece such as a symphony or a sonata, often in 3
4 time. The precise definition has varied over the years, but scherzo often refers to a movement that replaces the minuet as the third movement in a four-movement work, such as a symphony, sonata, or string quartet. Scherzo also frequently refers to a fast-moving humorous composition that may or may not be part of a larger work.
