Gamelan uses its own tone names (nem, pi, barang, etc.), not Western note names. Fixed tonic from C4 to nem4 and added pelog nem/barang modes. Replaced miyako-bushi with iwato and kumoi (actual scale names in the system). Added ValueError to exception handling. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
