But I have been seriously working on a new au called Tunetale!! I even wrote a summary of it that I will show you now:

So, Tunetale is an Undertale AU that is essentially one big musical!(with the characters singing songs that already exist because I refuse to make my own music hell no) Each character (with the exception of Frisk) has a music genre that they specialize in. It’s a fully pacifist AU and doesn’t have much angst in the actual main story.

Monsters are born with a voice ready to sing, having it imbued within their very SOULs. It’s so powerful that this talent emanates from them like an aura, allowing others to coordinate with them seamlessly, even if they’re just making up the song on the spot.

As such, singing is an important part of Monster culture like puzzles. In fact, singing is required in order to solve all the puzzles they make. This cultural aspect is not only a way of expressing oneself, but also a way of communicating your “true feelings.”

Sometimes Monsters can hit the “Perfect Harmony” or just “Harmony” for short, which can only happen if the singers are in complete sync with each other mentally and physically. It is a powerful thing to achieve, allegedly being able to bring people back from the dead or from serious injury. Their styles will meld, creating a balanced, harmonious song. An example is if Sans and Papyrus were to hit a Harmony, their music styles would merge into a Funk-R&B combo, with their auras pulsing a blue and orange combo with the beat. A Perfect Harmony can establish strong bonds between Monsters.

Even though each Monster specializes in one music genre specifically, they are not limited to singing only that one for their whole life. In fact, excelling in music that is out of your comfort zone is seen as a very attractive trait for Monsters of all kinds.

Musical skill varies on when it blooms for a Monster, sometimes late and sometimes early, but it will always come along eventually.
