Toby Fox's Undertale uni(multi?)verse uses leitmotifs A leitmotif is a repeated musical expression (melody, instrument, rhythm, etc.) found throughout a particular work. to establish themes and connections, and to enhance the plot and themes of the story.
This index aims to catalogue said usage of leitmotifs to the best of my ability. In doing so, I hope to create a comprehensive resource for anyone to reference in regards to theorycrafting and other discussion.
Of course, I am far from the first to attempt this, and I would like to give thanks to those who I can base and double-check my work off of:
JakobTheQuizGuy,
MediaMotifs,
LL Game Shows!,
Jason M. Yu,
Alex Yard,
Andrew Cunningham,
and all of the contributors to the Undertale and Deltarune Wikias.
I'd also like to personally thank the Andrew Cunningham Discord Server for helping to make this index a reality.
(Indirectly and unknowingly, via inspiration and boredem-reduction through shenanigans)
In particular, I thank Awesome Possum and Trondor for their participation in leitmotivic discussion and analysis.
Please do keep in mind three things:
Use your own judgement when reading through, and especially if you plan to cite this index elsewhere!
(Also, feel free to contact me via discord or e-mail to discuss/correct any disagreements/inaccuracies/typos you find)

Throughout this index, in order to ease confusion when talking about songs versus motifs, song names are italicized, whereas the names of leitmotifs are put in single quotes, like so:
The 'Ruins' leitmotif first makes its appearance in the song Ruins.
'Ruins' later appears in Waterfall alongside 'Another Medium'.
The index itself is split into various articles:
Right now, this index is in its early stages, and therefore only contains rough overviews of most leitmotifs in the Undertale and Deltarune soundtracks, with little analysis.
I also hope to have a listing of all of the UT/DR songs, in addition to some sound files and extraneous tracks.
What form said track listing will take is unclear, but hypothetically each song would have links to the relevant leitmotifs, and some general information (key, bpm, time signature, trivia, etc.), akin to the Undertale wiki.
