Some modern musicians and composers, including new age and experimental artists, have incorporated the instrument's unique sound into their works. Additionally, it can be occasionally heard in certain folk, jazz, and ambient music pieces.

Overall, the glass harmonica is primarily associated with classical music but can be found in a variety of genres depending on the artist and their creative vision.
