Researchers have introduced SymphonyGen, a novel 3D hierarchical framework designed for generating complex orchestral music. This system addresses limitations in existing models by decomposing music generation across bar, track, and event axes, enhancing scalability and steerability. SymphonyGen incorporates a controllable harmony skeleton for structural guidance and uses reinforcement learning with audio-perceptual rewards to align symbolic output with acoustic expectations, also employing a dissonance-averse sampling algorithm.
