Rewrite O Fortuna in conductor-style matching Beethoven's 5th approach
Following the uploaded lead sheet, rewrote O Fortuna with: - Continuous harmonic bed (sustained string chords throughout) - tutti() and choir4() helpers for full orchestral/SATB choir hits - Running string arpeggios as background texture (not hittable) - 9 sections following the score structure with tempo changes (ff opening → pp verses → mp building → f marcato → ff climax → fff finale) - Duration expanded from ~35s to ~95s - Only main choral melody accents are hittable (conductor experience) https://claude.ai/code/session_01TFVkxq4PYhkSFGYHEi4uqY
