In the Wake of Poseidon

K: Dmin T: 100 TS: 4/4 INST: Mellotron (strings/choir), Hammond organ, Electric guitar, Bass guitar, Drums, Lead vocal Mood: Brooding, epic, maritime, melancholic, slightly ominous/majestic Structure: Verse–Chorus–Instrumental/Bridge (A–B–A–C), with extended instrumental passages and textural development Summary: "In the Wake of Poseidon" suggests early-70s symphonic/progressive rock with dark, nautical themes. The arrangement centers on Mellotron strings/choir and Hammond organ for orchestral texture, a steady rock rhythm section (bass + drums), and electric guitar for accenting riffs and solos, plus a dramatic lead vocal. A moderate tempo (around 100 BPM) in a minor key (D minor/Aeolian flavor) fits the somber, ceremonial tone; 4/4 is the likely underlying meter with possible brief metric or feel shifts in instrumental sections. Structurally, expect verse/chorus vocal sections interleaved with longer instrumental passages and dynamic contrasts typical of King Crimson–era prog.
