交响曲
交响曲一词来自希腊语“symohonia”，原为“声音一起响”之意，这是一种按照奏鸣曲原则构成的管弦乐套曲形式。交响曲以结构宏大，内容深刻而富于戏剧性、管弦乐写法复杂而音色对比鲜明为特色。
第一乐章。奏鸣曲式，音乐活跃，充满戏剧性，由两个对立主题作呈示、展开和再现，示意矛盾的起因、发展和暂时的结果。
第二乐章，三段体或变奏曲，曲调缓慢如歌，内容往往表现生活的体验和哲理性的沉思，是交响曲抒情的中心段落。
第三乐章，常用小步舞曲或谐谑曲，音乐体现了矛盾冲突之后的闲暇、休整和娱乐。
第四乐章，多采用回旋曲式、奏鸣曲式或回旋奏鸣曲式，内容与矛盾的结果有关，常表现乐观、肯定的态度和胜利凯歌般的节日欢庆场面。
