Ori Eta

Ori Eta is essentially the musical identity for the Undertale soundtrack. The project is led by Toby Fox, who created both the game and its music. The soundtrack includes tracks like 'Undertale' and 'Megalovania' that became particularly well-known among players.

Fox has maintained a fairly private approach to his work, which has led to various interpretations of the music's themes. The sound blends simple melodic writing with chiptune and other electronic elements, creating a distinctive atmosphere for the game.

After Undertale, Fox continued with similar projects like the Deltarune soundtracks. The music from these games tends to resonate with players because it's so directly tied to the experience of playing them.
