As always, I strongly suggest listening to this track before watching my music theory analysis video (if you are not already familiar with it).
For your convenience, I have pulled the sheet music, chord charts, and any other especially salient diagrams from the analysis and posted them below.
1: A Section (1/2) Patterns in melodies and modulations throughout the A section.
2: A Section (2/2) Variation in the A section chord progression produces a more gradual, and thus darker-sounding, return to the original key.
3: B Section (1/2) High register cluster voicing imitates the harmonic structure of bright timbres.
4: B Section (2/2) Patterns in melodies and modulations throughout the B section (compared with A section's melodies and modulations).
5: C Section The C section's IV / V patterns imitation the 'positive tension' of the upward moving modulations the A/B sections.
6: D Section (1/2) Patterns in melodies and modulations throughout the D section - smaller leaps than the A/B/C sections.
7: D Section (2/2) Variation in the D section progression reveals latent symmetry with the whole step changes and half step modulations in other sections.
8: Conclusion General overview of this song's characteristics.
