Thick As A Brick

K: Dmaj (modal shifts / frequent modulations) T: 120 BPM (approx.; sections vary between ~110–130) TS: 4/4 (primary; occasional meter shifts in sectional passages) INST: AcousticGuitar, ElectricGuitar, Flute, HammondOrgan/Piano, Bass, Drums, Percussion Mood: Whimsical, satirical, theatrical, epic, pastoral Structure: Through-composed / multi-section suite (long-form piece with recurring themes and sectional contrasts) Summary: "Thick As A Brick" is best treated as early‑70s progressive folk‑rock: long-form, theatrical, and episodic rather than a simple verse/chorus song. Expect acoustic fingerpicking and melodic flute leads over a solid rock rhythm section, with Hammond organ/piano color, electric guitar accents and dynamic shifts into heavier rock passages. Harmonic language centers around D major/modal colors with frequent modulations; the tempo sits in a moderate rock range (~120 BPM) while meters and feels change across sections. Arrange as a suite with recurring motifs, contrasting instrumental interludes, and dramatic dynamic builds to capture the original’s satirical, grand, and pastoral character.
