"Steve's dead now. From here on in, Steve's death will be represented by the oboe."
A leitmotif is a recurring piece of music (or at least melody) that represents a character, action, or theme. This is a well-established technique used in almost every medium that involves music and story. The leitmotif technique was invented (or at least perfected) by opera composer
Richard Wagner in the second half of the 19th Century where, in his operas, not only would every character have his/her own musical theme, but also objects, places, and even abstract ideas did too.
Leitmotifs are often named simply "<character>'s Theme" or "<noun> Motif"
note (though the name alone is not enough to establish it as a motif). They often make up the
bulk of movie and anime soundtracks, and a fair chunk of video game soundtracks as well.
This is different from an
Image Song in that Image Songs exist only outside of the scope of the show that produced them. Compare with
"I Am" Song.
If a character with a distinctive-sounding Leitmotif is in a production or episode with
No Fourth Wall (or at least some
Medium Awareness), one of his or her fellows may
make a comment on how loud and annoying their theme music is. (To which the character will almost always reply, "What theme music?") Can become a
Musical Spoiler for audiences if (or after) they recognize the theme. The character might also have their leitmotif as their own ringtone, for a subtler joke; see also
Left the Background Music On.
Note that if a character's leitmotif starts playing during an action scene,
start running.
Can become a
Recurring Riff when used throughout a long-running series.
Bootstrapped Leitmotif is such a variation, where a song that wasn't originally intended as a
Leitmotif later becomes one.
One especially common leitmotif in video games is the
Battle Theme Music, associated with monster battles in general. (Which also
happen a lot.) If a specific character's
Battle Theme Music is actually a remix of their
Leitmotif, it may be a
Boss Remix.
