Musical composition in which successively entering voices repeat or imitate one or more themes and the voice parts are interwoven in a continuous harmony. A fugue is a composition technique that involves imitating a melody at various intervals and pitches. It is the most known form of contrapuntal music, which means that there are distinct melodies being played at the same time. While fugues are typically used in orchestral compositions, they are also used in modern music as well.
