In music, monody refers to a solo vocal style distinguished by having a single melodic line and instrumental accompaniment. Although such music is found in various cultures throughout history, the term is specifically applied to Italian song of the early 17th century, particularly the period from about 1600 to 1640. The term is used both for the style and for individual songs (so one can speak both of monody as a whole as well as a particular monody). The term itself is a recent invention of scholars. No composer of the 17th century ever called a piece a monody. Compositions in monodic form might be called madrigals, motets, or even concertos (in the earlier sense of "concertato", meaning "with instruments").

In poetry, the term monody has become specialized to refer to a poem in which one person laments another's death. (In the context of ancient Greek literature, monody, μονῳδία, could simply refer to lyric poetry sung by a single performer, rather than by a chorus.)
