Codename S.I.X. was an ambitious Undertale fangame with a new setting and characters.

This especially long Pxtone track consists of six sections, establishing six simple motifs to represent the six souls or human characters that are central to the game's story and mechanics. These six motifs would have been reused and further developed in other tracks relating to these characters.

For the other composers, I transcribed each motif into hookpad and wrote up a description of how I thought each could be used:

Patience: www.hooktheory.com/hookpad/view/cpZLPukYiEur
(Starts at 0:00)
I tried to represent the duality of patience with a serene, calm idea with a little bit of dissonance. This could easily be used in a grander, more frightening context (like 0:15 but with scarier chords, etc.) as well as a calm reflective context.
Bravery: www.hooktheory.com/hookpad/view/QMhbdhhWZkdl
(Starts at 0:38)
The steady, unchanging ostinato over the intense groove and chord changes symbolizes bravery in an intense or dangerous situation. Not much of a melody but the idea could certainly be used elsewhere.
Integrity: www.hooktheory.com/hookpad/view/Sb2Mdha7G-Sm
(Starts at 1:14)
I used a sort of music-box arrangement to fit with the ballet imagery. The rhythms are pretty steady, which fits with the “integrity” concept. I could see this fitting well into a grand, triumphal context; the IV chord in a minor key gives it a feeling of “success from the jaws of defeat”.
Perseverance: www.hooktheory.com/hookpad/view/H7EcVkPE2yog
(Starts at 1:44)
This one has sort of a slow, plodding groove and a drawn-out melody to represent perseverance. There's no exact structure in terms of how the melody fits over the chords at the beginning, but there's a few repeated patterns. The transition chords not included on the hookpad are just a matter of arrangement, anything could be put (or not put) there.
Kindness: www.hooktheory.com/hookpad/view/zgCDGoYX9iiu
(Starts at 3:00)
The short, repeating set of chords and the warm, mellow arrangement elicit feelings of “kindness”. Some kind of a soft piano arrangement would probably suit this as well.
Justice: www.hooktheory.com/hookpad/view/oVytTfDOF-XM
(Starts at 4:08)
Tried to play into the “cowboy” theme, especially with the last two chords. It's upbeat and happy, personifying a character who goes into action to save people.
