## What is WS Instrument Atlas?

Explore 114 musical instruments in six categories with an atlas designed for shared learning.

Discover each instrument’s name, era, origin, tone, playing method, care and interesting facts. Search in English, Korean, Japanese or Spanish, and compare two instruments side by side.
