Hang: A 21st Century Percussion Instrument

If you've never heard the Hang, you're missing one of the most fascinating instruments of the 21st century. Felix Rohner and Sabina Schärer invented it in Bern, Switzerland in 2000, crafting it from nitrided steel shells that produce an otherworldly, crystalline resonance. Buying one required mailing a handwritten letter — with no guarantee you'd ever get one. Its near-impossible acquisition fueled a global wave of independent makers. There's far more to this remarkable story waiting ahead.

Key Takeaways

• The Hang was created in 2000 by Felix Rohner and Sabina Schärer of PANArt Hangbau AG in Bern, Switzerland.
• Inspired by steel drums and the ghatam, the Hang was publicly debuted at Musikmesse Frankfurt in 2001.
• Its two deep-drawn steel half-shells form a convex-lens shape, producing a crystalline, layered sound with rich harmonics.
• PANArt never exceeded 400 instruments annually; buyers had to mail handwritten letters and await rare invitations to purchase.
• Viral YouTube videos from 2005 onward sparked global fascination, inspiring hundreds of independent makers worldwide to create "handpans."

Where the Hang Came From and Who Invented It

The Hang was developed in Bern, Switzerland, by Felix Rohner and Sabina Schärer, the duo behind PANArt Hangbau AG. If you explore their inventor biographies, you'll find that Rohner began building steel pans as early as 1976, giving the pair decades of manufacturing expertise before the Hang ever existed. Together, they supplied Swiss steel bands throughout the 1980s and 1990s.

Origins documentation traces the instrument's earliest prototypes to around 1999–2000, when experimentation with deep-drawn steel sheets began in earnest. Swiss musician Reto Weber also played a pivotal role, proposing the concept of a hand-playable instrument combining steel drum tones with ghatam-like playability. His visit to the PANArt workshop catalyzed the shift away from traditional steel pans, ultimately leading to the Hang's public debut at Musikmesse Frankfurt in 2001. The Hang's signature tone emerged from its deep-drawn metal shells, which were carefully tuned and formed to allow the bowls to vibrate in multiple ways, producing a uniquely complex sound. Much like the HP 200A audio oscillator, which used a simple light bulb to stabilize its Wien bridge circuit and kept distortion below 1% across a wide frequency range, the Hang achieved acoustic precision through an elegant and unconventional technical solution.

The Hang vs. the Handpan: What's the Difference?

Although many people use "Hang" and "handpan" interchangeably, they're actually distinct terms with different scopes. Here's what separates them:

1. Origin – PANArt exclusively makes the Hang; multiple makers produce handpans worldwide.
2. Materials – The Hang uses nitrided steel, while handpans incorporate stainless, raw, or hybrid steels.
3. Modal scales – Handpans offer varied tone field numbers and scale options; the Hang emphasizes pentatonic-based designs.
4. Performance techniques – The Hang requires a light, controlled touch to avoid detuning, while handpans accommodate tapping, gliding, and even mallets.

The term "handpan" emerged around 2007 to describe the broader instrument family without infringing on PANArt's trademark. Understanding the distinction helps you choose the right instrument for your musical goals. The Hang was created in 2000 by Felix Rohner and Sabina Schärer, drawing inspiration from steelpan drums, gongs, and Indian ghatams.

How the Hang Produces Its Crystal Resonant Tone

When you strike a tone field on the Hang, the metal's elasticity causes it to vibrate in multiple simultaneous modes, each contributing a distinct layer to the instrument's crystalline tone.

The fundamental frequency anchors the pitch, while harmonics at precise 1:2:3 ratios create sympathetic resonance across adjacent tone fields, enriching each note with subtle harmonic complexity.

You're effectively playing one note while the instrument quietly activates others.

The convex steel body drives Helmholtz amplification, functioning like a violin's chamber to shape and project sound outward.

High frequencies travel upward from the tone fields, while low frequencies exit through the bottom port. Tracking these acoustic changes over time is similar to how athletes use body composition monitoring to detect subtle physiological shifts that would otherwise go unnoticed.

Together, these interactions explain why each struck note blooms into something far richer than a single pitch. Non-linear behavior at high dynamics introduces additional harmonics and subtle pitch shifts, lending the instrument a natural expressiveness that responds to the force of each strike.

What Makes the Hang's Nitrided Steel Shell Acoustically Unique

What sets the Hang's shell apart from other handpans begins with a process called high-temperature nitriding, where PANArt diffuses nitrogen deep into carbon steel's surface. This treatment creates a hardened exterior while preserving the core's elasticity, producing tonal contrast you can hear and feel. The result delivers four acoustically distinct advantages:

1. Increased surface hardness accelerates energy release, giving you a sharp, immediate attack.
2. Adjacent tone fields couple acoustically, enriching harmonic depth.
3. Shorter decay creates a grounded, earthy timbre darker than untreated alternatives.
4. Non-linear behavior at high dynamics adds expressive, raw metallic character.

You'll also notice the finished shell carries a gray or bluish hue—a visible signature of nitriding's transformative effect on both aesthetics and sound. The Hang is constructed from two steel half-shells, deep-drawn and glued at the rim to form its signature hollow convex-lens shape.

How Each Note on the Hang Is Tuned by Hand

Shaping each note on the Hang begins with hammering elliptical tone fields into the steel shell, where a central dome establishes the fundamental frequency. From there, axis specific hammering targets each directional axis to set distinct overtones: the long axis carries the octave, while the short axis produces the compound fifth. These three tones align at a 1:2:3 ratio, creating harmonic coherence across every note field.

You verify each frequency using a strobe tuner while exciting specific axes by hand. Multiple hammering passes refine the pitch after initial shaping, but early tuning causes slight pitch drift. Kiln stabilized settling follows, where heat loosens the metal, allowing final adjustments to lock in. High notes may also carry alternative harmonics, like a compound third, depending on the scale configuration.

The Hang was developed by Felix Rohner and Sabina Schärer of Bern, Switzerland, whose years of research into the steelpan directly informed the tuning methods and acoustic principles applied to each tone field.

Why Buying a Hang Meant Writing a Letter and Waiting Years

Acquiring a Hang required something most modern transactions don't: a handwritten letter mailed directly to Felix Rohner and Sabina Schärer at PANArt Hangbau AG in Bern. Letter patience wasn't optional—it was mandatory. With roughly ten letters arriving daily, PANArt processed them in batches after set reply deadlines.

Here's what you needed to accept:

1. No waiting lists existed to track your position
2. PANArt periodically selected buyers, not first-come candidates
3. A positive reply meant workshop invitation, not purchase guarantee
4. Invitation uncertainty remained constant; refusal letters went to thousands annually

Uninvited visits weren't permitted. You couldn't arrive, try one, and buy. PANArt's handcrafting process simply couldn't accommodate immediate demand, making patience the only real strategy. Annual production never exceeded 400 Hang per year, meaning global demand would always vastly outpace what two makers could realistically build and deliver.

Why the Hang Inspired a Global Wave of Handpan Makers

The Hang's near-impossible acquisition process didn't suppress demand—it amplified it. When PANArt ceased production around 2013-2014, makers worldwide seized the opportunity to replicate its design and sound. They began crafting what's now called "handpans," a term deliberately distinguishing their instruments from PANArt's trademarked Hang.

You can trace this global wave back to viral YouTube videos that circulated from 2005 onward, exposing millions to the Hang's ethereal sound. That exposure created insatiable demand that PANArt's strict policies couldn't satisfy. Independent builders experimented with steel sheets, developed community workshops, and even produced DIY kits, pushing the instrument into diverse scales spanning Middle-Eastern to blues traditions. By the 21st century, hundreds of makers had emerged across continents, transforming a single Swiss innovation into a worldwide percussion phenomenon. The instrument's origins trace back to Bern, Switzerland, where Felix Rohner and Sabina Schärer first developed it in 2000.
