Oh! One True Love – Undertale

About game/music

This is “Oh! One True Love” from the 2D RPG “Undertale” produced by Toby Fox.

If you listen to the scene and the song together in the game, you’ll notice that it’s clearly an homage to the opera scene in FinalFantasyVI.
The song that follows, “Oh! Dungeon,” also seems to be an homage to the game’s “Grande Finale”.

The original is in the key of A major, but since the melody is high, I lowered it and put a capotast on the 5th fret, F major.


bar 9~12:

  • iv in major key (other Tabs include this)
    • one of the subdominant minor chords, which include b6th of main key.
    • It’s nostalgic or romantic.
    • Typically used following IV.
    • It’s borrowed mostly from parallel minor, but also from Mixolydian b6 or Harmonic Major (in this case, ivM7)
