"False Knight" has a menacing drums-and-violin version of the "Hollow Knight" motif at the start and manages to maintain the loud and fast rhythm of the instruments all throughout the song, in order to correspond to how gigantic the False Knight is with that armor.
The chorus, or the part where the track progresses at its loudest and fastest point, can be heard starting from the 1:21 timestamp of the video. The major leitmotif is there, but this song also justifies the overall upbeat nature of itself since Zote thinks so high of himself that his boss theme lacks the persisting sad, gloomy and depressing melody of "The Hollow Knight" theme. Ironically, this is the leitmotif of Grey Prince Zote, the game's Lethal Joke Character of a boss who has delusions of grandeur, thinking that he is a Knight in Shining Armor (which Bretta also believes).
"Truth, Beauty and Hatred" is by far the most triumphant rendition, evoking the feeling of knights marching to war with drums, violins and trumpets.
It is as if this is one of the tracks that you can hear in a church ceremony. The chanting is clearer and more prominent this time, with less of the imposing vibe of the original, symbolizing the literal purity or glory of the Pure Vessel.
"Pure Vessel", the theme for The Hollow Knight in their prime, is a choral arrangement of "Sealed Vessel".
