Think of each movement as a separate thread, each with its own priority queue of notes. The processor is the orchestra pit—time slices are your beats. You want to minimize context switches, so bundle harmonies that share instruments into the same cache line. Cache your most repeated motifs in L1, and stream long passages from L2. Use a branch‑predictive algorithm for dynamic tempo changes: pre‑compute the most probable rhythmic patterns and load them ahead of time. Finally, keep the whole score in a balanced binary tree so you can jump to any movement in logarithmic time. That way the CPU runs the symphony with minimal latency and maximum elegance.
