Through-composed music is relatively continuous, non-sectional, and/or non-repetitive. A song is said to be through-composed if it has different music for each stanza of the lyrics. This is in contrast to strophic form, in which each stanza is set to the same music. Sometimes the German durchkomponiert is used to indicate the same concept.
Many examples of this form can be found in Schubert's "Lieder", where the words of a poem are set to music and each line is different, for example, in his Lied "Der Erlk nig" ("The Elf-King"), in which the setting proceeds to a different musical arrangement for each new stanza and whenever the piece comes to each character, the character portrays its own voice register and tonality. Another example is Haydn's 'Farewell Symphony'.
"Happiness Is a Warm Gun", by The Beatles, is an example of this form's application in popular music. Furthermore, a good deal of Captain Beefheart's oeuvre is through-composed. No section of Ary Barroso's 1939 samba "Brazil" repeats; however, a second set of lyrics in Portuguese allows the melody to be sung through twice.
The term is also applied to opera and other dramatic works involving music, to indicate the extent of music (as opposed to recitative and dialogue). For example the musicals of Stephen Sondheim and Andrew Lloyd Webber have been part of a modern trend towards through-composed works, rather than collections of songs. In musical theater, works with no spoken dialogue, such as Les Mis rables are usually referred to by the term "through-sung."
A work composed chronologically (from the beginning of the piece to the end, in order) without a precompositional formal plan is also through-composed.
