Tsüan

Tsüan is a lesser-known traditional musical instrument originating from the Tsolyáni people, a fictional ethnic group from the science fiction universe of *The Expanse*. The instrument is primarily featured in the series' soundtrack, composed by Miguel Colom, and is designed to evoke a sense of cultural authenticity and mystique for the Tsolyáni civilization.

The Tsüan is described as a stringed instrument, resembling a cross between a lyre and a zither, with a distinctive, resonant sound that complements the series' ambient and orchestral score. Its name is derived from the Tsolyáni language, reflecting the fictional linguistic diversity of the *Expanse* universe. The instrument is often used in ceremonial or musical contexts within the narrative, reinforcing the cultural identity of the Tsolyáni.

While the Tsüan is entirely fictional, its inclusion in *The Expanse* serves to enhance the world-building by providing a unique auditory element tied to the Tsolyáni people. The instrument’s design and sound are crafted to align with the show’s aesthetic of blending advanced technology with ancient traditions, embodying the Tsolyáni as a civilization that values both innovation and heritage.

Fans and musicians have occasionally recreated or reinterpreted the Tsüan’s sound using modern instruments, such as guitars or synthesizers, to capture its imagined musical character. However, no physical or widely documented prototype of the instrument exists outside of the series' fictional universe. Its legacy lies primarily in its cultural representation within *The Expanse*, contributing to the rich tapestry of its fictional world.
