Easily my favourite part is 3:13.
Starting in E MINOR, from 2:40 the track goes into Eb MAJOR. 1fin literally transposes smoothly into a key sig that should not work, and it stays in Eb for a while before returning. Sir, how?
From there it goes to the IV, Ab major and then F minor. (2:57, 3:05) How have we ended up from E minor, to playing in keys exactly 1 semitone above and below (F and Eb) without any clashes? I can't stress this enough.
But that's not all.
3:13 The track shifts into C minor/Ab major, and comes back to Eb major with some awesome sfx. So we've seen a progression from E --> Eb, then I - IV - II - VI - IV - II - I.
3:25 BOOM then it goes into Db major (VII) with jazzy chords and back into C minor.
3:33 Now it just randomly shifts into Gb/F# major, (which btw is a tritone above C. again ??) and goes to Eb MINOR 3:38. So now we just arrive in Eb minor when some chords ago we were in Eb major. (I think it went I - VII - VI [transpose to minor] - III - I)
And just to flex again, 3:44 1fin just plays 3 piano keys to transpose back into home key of E, but now in major ??? And, tritones again 3:51! The key of C major is achieved, and EVERY IV (F) THAT HE PLAYS IN THE THEME IS REPLACED WITH F# INSTEAD. This should sound absolutely horrible but it sounds the complete opposite.
(3:59 Smoothly transposes back home)
Man I don't know what to say about this. All these 'harmonic' songs with 'awesome chords' can go just get rolled by this piece instead.
