Fuller Beethoven's 5th orchestra: harmony voices, woodwinds, horns
Replaced thin orch() helper (strings + brass + bass) with tutti() that creates 5 simultaneous voices per note: - 1st violins (melody), trumpets (doubling), 2nd violins (5th below), clarinets (3rd below), cellos/basses (octave below) Added between sections: - Horn pad (sustained Eb+G brass) on held notes - Woodwind countermelody (clarinets in 3rds) on soft restatement - Viola parallel motion on scalar passages - Bass walking on downbeats during runs - Full 3-note chord voicings on power chord section (was 2-note) - Choir with harmony voices (Eb+G+C) on recapitulation - Brass + strings + choir triple-layered on final chord Background nodes: 438 → 565 (29% more orchestral depth) Same 113 hittable melody notes, same 54s duration. https://claude.ai/code/session_01GdFrFqAe9e2DaJ86jZPEZE
