Incidental music is music in a play, television program, radio program, video game, film or some other form not primarily musical. The term is less frequently applied to film music, with such music being referred to instead as the "film score" or "soundtrack".
Incidental music is often "background" music, and adds atmosphere to the action. It may take the form of something as simple as a low, ominous tone suggesting an impending startling event or to enhance the depiction of a story-advancing sequence. It may also include pieces such as overtures, music played during scene changes, or at the end of an act, immediately preceding an interlude, as was customary with several nineteenth-century plays. It may also be required in plays that have musicians performing on-stage.
The use of incidental music dates back at least as far as Greek drama. A number of classical composers have written incidental music for various plays, with the more famous examples including Ludwig van Beethoven's Egmont music, Franz Schubert's Rosamunde music, Felix Mendelssohn's Midsummer Night's Dream music, Georges Bizet's L'Arlésienne music, and Edvard Grieg's music for Henrik Ibsen's Peer Gynt. Parts of all of these are often performed in concerts outside the context of the play. Vocal incidental music, which is included in the classical scores mentioned above, should never be confused with the score of a Broadway or film musical, in which the songs often reveal character and further the storyline. Since the score of a Broadway or film musical is what actually makes the work a musical, it is far more essential to the work than mere incidental music, which nearly always amounts to little more than a background score; indeed, many plays have no incidental music whatsoever.
Some early examples of what were later called incidental music are also described as semi-operas, quasi-operas, masques, vaudevilles and melodramas.
The genre of incidental music does not extend to pieces designed for concert performance, such as overtures named after a play, for example, Beethoven's Coriolan Overture (written for Heinrich Joseph von Collin's tragedy), or Tchaikovsky's Romeo and Juliet fantasy-overture.
Modern composers of incidental music include John White and Lorenzo Ferrero.
Famous quotes containing the words incidental and/or music:
“Besides, our action on each other, good as well as evil, is so incidental and at random, that we can seldom hear the acknowledgments of any person who would thank us for a benefit, without some shame and humiliation. We can rarely strike a direct stroke, but must be content with an oblique one; we seldom have the satisfaction of yielding a direct benefit, which is directly received.”
—Ralph Waldo Emerson (1803–1882)
“La la la, Oh music swims back to me
and I can feel the tune they played
the night they left me
in this private institution on a hill.”
—Anne Sexton (1928–1974)
