They Who Govern Reason, the boss battle theme for the four gods guarding the advanced hero jobs.It switches from dark and foreboding, to capture the power and menace of your final adversaries, to soaring trumpet and flute solos to depict the protagonist's determination in the face of daunting odds. Battle at Journey's End plays during Chapter 4 bosses.It retains the string emphasis but underlines it with electric guitar and piano. Decisive Battle 2 plays during more serious bosses, like Therion's boss Heathcote.(All the other boss themes are straight rock arrangements.) It is the most traditionally classical of the themes, predominated by strings with accents in horns and piano it starts out with a traditional classical marching snare before transitioning seamlessly into Rock Music drumming. Decisive Battle 1 plays during the less intense bosses of the early game (from a story perspective Mikk and Makk, Those Two Guys, get this music despite being one of the more difficult bosses in terms of gameplay).There are four different boss battle themes all written in that same tempo and (starting) key but each with their own styles and flourishes.This also helps hype the battle just when you thought you'd come to the end of the song, it spirals off in a completely new direction. But Octopath Traveler's boss themes also have first and second endings: the first time you go through the loop, it culminates in certain material before looping, and the second time it ends with different material before looping. Music already has a notation for that: repeat symbols. The defining quality of video game music is that it loops each song is written to repeat endlessly, because the devs have no idea how long any given player will spend in any given situation. Each boss battle theme has a Meta Twist.

The seamless transition hypes the battle immensely. The effect is discussed here in prose and here on YouTube. First off, Nishiki wrote eight introductory themes, one for each character which uses their signature instrument and evokes their personal theme, in same key and tempo as the boss theme these introductory themes play underneath the pre-battle conversations and then segue seamlessly into the boss theme itself.The boss battle themes in this game could easily be the subject of a dissertation.Strains of it pop up in a number of other pieces, and it's heard a few times throughout the game. The Main Theme captures the spirit of wanderlust the game as a whole wants to evoke.It's a little bit tempting to just link the whole OST, as Yasunori Nishiki hit the proverbial ball out of the park and toward the moon on this one.
