Играющий 3D-оркестр из 43 музыкантов с единым таймером воспроизведения

Build a playable 3D orchestra scene in the browser. Start from an original short piano melody and expand it into a 15-part arrangement performed by 43 musicians and a conductor. Place a grand piano with its pianist near the front, string, wind and brass sections in arc formation around it, and a conductor's podium, all on a round grey stage ringed by tall pale acoustic panels against a black background. Every musician is a simple posed figure with its instrument and animates in time with its part. One shared playback clock drives all parts so the music and the movement stay in sync. Add play and pause, and camera controls to orbit, zoom and pan around the stage. Keep a neutral grey, cream and orange palette with clear soft lighting. Deliver it as a single web page with synthesized audio. Done when all 15 parts play together and the camera can circle the ensemble.
