Use `analyze_voice_conduction` to check how notes move between two chord voicings. It runs classical harmonic principles against your input, telling you exactly where the melodic line breaks down. You can also use `check_voice_hierarchy` and `evaluate_smoothness`. These functions validate that voices stay in proper ascending order while making sure the overall transition isn't jarring.
