Having guitar background, for me it's natural to learn the chord progression of the composition (in C-dur). But there are a few that are hard to identify for me, in the climax parts, marked by ???:
[: C Dmi7/C G7/B C :] A D7/C G Cmaj7/B Ami7 D7 G7 G°7 Dmi7/F F°7 C/E Fmaj7/E Dmi7 G7 C C7 Fmaj7 F#°7 ??? ??? G7 C/G G7sus4 G7 ??? C7 F/C G7/C C
measures 27 (G, E♭, B, C, E♭), 28 (A♭, F, B, C, D) and 33 (G, E♭, A, C, F♯). What chords are these?
