An open book on the history of classical music features a cello, sheet music, and tiny musicians under warm lighting

Prompt

1. The Anchor:
   A massive, hyper-realistic Cello or Upright Bass stands vertically in the book crease.
   Transition: The top of the Cello neck fades into a technical drawing on the wall; the body is real wood on the floor.

2. The Background (Vertical Page):
   Strict 2D: No wood paneling. Just aged paper.
   Sketches: Da Vinci-style technical diagrams of Acoustic Waves, Seating Arrangements, and Musical Notation.

3. The Foreground (Horizontal Page):
       A crumpled Playbill/Program.
       A block of Violin Rosin.
       A pair of Opera Glasses.
       A Conductor's Baton lying across the page.
   The Figures: Tiny musicians standing on the sheet music page or on the curve of the Cello, not on grass.

4. Lighting:
   Warm, golden "Concert Hall" lighting, reflecting off the varnish of the Cello.
