How a Handpan Produces Sound

The handpan is an idiophone — a family of instruments where the body itself vibrates to produce sound, like bells or gongs, rather than strings, membranes, or air columns. It consists of two convex steel shells glued together at the rim, forming a sealed resonance chamber. The top shell carries a central dome (the Ding) and a ring of concave tone fields; the bottom shell has a single tuned hole called the Gu, which releases the bass resonance and gives the instrument its characteristic warm sustain.

When a tone field is struck, the steel surface vibrates in a complex pattern shaped by the curvature hammered into it. A well-tuned tone field produces three frequencies simultaneously: the fundamental pitch, its octave (2× the fundamental), and a compound fifth (3× the fundamental). It is this precise three-frequency alignment — achieved by a tuner making hundreds of controlled hammer strikes — that gives the handpan its rich, chorus-like bell tone. Crucially, the metal in each tone field is under compressive stress, not tension like a drum skin — the field pushes outward against its rim, and the controlled curvature determines the pitch.

The hollow chamber acts as a Helmholtz resonator, amplifying the tone fields and blending their overtones into a coherent, room-filling sound. Because all tone fields on a handpan share overlapping harmonics, notes played together naturally reinforce each other — which is why every combination sounds pleasing and there are essentially no "wrong" notes to hit.

Types of Handpan

The original instrument was the Hang®, created by PANArt in Bern, Switzerland in 2000. Today the broader family of similar instruments is called handpans, and makers worldwide have introduced several distinct variants:

• Standard handpan (8–9 notes): The classic format — one Ding plus seven or eight outer tone fields. Most are 53–55 cm in diameter, tuned to a single diatonic scale. D Minor (D Kurd) is the most common tuning.
• Mutant handpan (12–22 notes): Extra tone fields are fitted between the standard ring or around the Ding, giving a wider melodic range. The instrument is physically larger and typically harder to tune, making these rarer and more expensive.
• Double-sided / bottom-note handpan: Tone fields are also crafted onto the lower shell, effectively doubling the note count. The player can flip the instrument or reach underneath for the extra notes.
• Mini handpan (46–48 cm): A smaller-diameter instrument producing higher pitches. Popular for travel and with younger players.
• Steel tongue drum (related): Often confused with the handpan, the steel tongue drum has tongues cut directly into a cylindrical steel shell rather than hammered tone fields. Its sound is brighter and more metallic, and it is typically played with mallets rather than bare hands. The samples powering this virtual instrument are from a steel tongue drum — a close cousin with a similar resonant character.

Materials and Construction

Most handpans are made from nitrided steel — steel that has been heat-treated in a nitrogen atmosphere to harden the surface and stabilise the tuning. Some makers use raw steel or stainless steel; stainless instruments are more resistant to rust but are considered harder to tune. Tuning a single instrument takes hundreds of carefully placed hammer strikes and can require days of work, which is why a quality handpan typically costs between $1,500 and $5,000 or more. Even after purchase, handpans can drift out of tune over time due to temperature changes or physical impact, and must be periodically re-tuned by a specialist.
