The hang drum, also known as a hang or handpan, is a musical instrument created in the early 2000s by Felix Rohner and Sabina Schärer in Switzerland. It is made from two metal hemispheres that are welded together, forming a hollow shell. The instrument produces soothing, melodic sounds when struck with the hands, making it popular for both solo performances and group settings. Hang drums are typically tuned to specific scales, allowing for a range of musical expressions. They are often used in various genres, including world music, ambient, and meditative practices. Their unique sound and portability have contributed to their growing popularity among musicians and enthusiasts worldwide.
