Gamelan Slendro/Pelog Tuner

Gamelan Slendro/Pelog Tuning Explorer

IMPORTANT DISCLAIMER: This tool is an **educational demonstrator**, not a precise tuner for physical Gamelan instruments. Gamelan tuning (Slendro and Pelog) is highly **relative and non-standardized**, varying significantly between regions, ensembles, and even individual instruments.

The frequencies provided are **approximations** based on common theoretical representations and research for a specific reference pitch. They will **not** perfectly match any actual Gamelan set, which are tuned by ear to sound right *together* and often feature intentional acoustic "beating" for their unique sound.

Use this tool to explore the *characteristics* and *intervals* of these fascinating tuning systems.
