How Are Handpans Made? A Step-by-Step Guide to Crafting Handpans

The handpan, also known as the hang drum, is a mesmerizing percussion instrument cherished for its ethereal, melodic tones and captivating resonance. While it looks simple, its creation is a meticulous process requiring craftsmanship, precision, and a deep understanding of acoustics. This guide will walk you through the step-by-step process of making a handpan, from selecting raw materials to final tuning.

1. Material Selection and Preparation

The foundation of a handpan begins with high-quality steel. The steel type significantly affects the instrument’s durability, resonance, and tonal quality.

  • Nitrided Steel: Most traditional handpans are crafted from nitrided steel, a heat-treated material that enhances strength, corrosion resistance, and stability.
  • Stainless Steel: Modern makers sometimes prefer stainless steel for its resistance to rust and its brighter, longer-sustaining tones.

The Nitriding Process

  • The steel sheets are exposed to nitrogen gas at high temperatures. This process hardens the surface, creating a material that produces cleaner and more stable vibrations when struck.

2. Shaping the Steel Shells

Handpans are made of two half-shells that are shaped to form the instrument’s body.

Forming the Dome

  • Hydroforming or Deep Drawing: In professional workshops, machines press flat steel sheets into a domed shape using extreme pressure or water force.
  • Manual Hammering: Alternatively, some handpan makers use traditional methods, manually hammering the steel into shape—a time-consuming process that requires precision.

The upper shell forms the tone fields and the central note (ding), while the lower shell often has a hole (gu) for sound resonance.

3. Marking and Crafting the Tone Fields

The tone fields are the oval or circular areas on the handpan where specific notes are tuned. The precise placement and shape of these fields are critical to the instrument’s sound.

Steps to Create Tone Fields

  • Marking: The desired positions of the tone fields are drawn onto the upper shell, carefully measured to ensure accurate spacing.
  • Shaping: Each tone field is carefully hammered to create a slight indentation. This step helps define the pitch and allows the metal to vibrate at specific frequencies.

Crafting these indentations involves hours of controlled hammering, using both mechanical tools and manual techniques.

4. Initial Heat Treatment

Once the shells are shaped and tone fields are defined, the instrument undergoes heat treatment to stabilize the material and improve its resonance.

  • Annealing: The steel is heated to a high temperature and then cooled gradually. This process helps relieve internal stress caused during shaping and hammering.
  • Tempering: For nitrided steel, this additional step helps achieve the proper hardness without making the material brittle.

This stage ensures that the handpan maintains its structural integrity and produces clean, consistent tones.

5. Tuning the Notes

Tuning is arguably the most complex and essential stage in the handpan-making process. It requires both technical expertise and a finely tuned ear.

The Tuning Process

  1. Defining the Fundamental and Harmonics: Each tone field is tuned to produce a fundamental note as well as its harmonics (octave and fifth).
    • Hammering specific points of the tone field adjusts the pitch.
    • The artisan uses electronic tuners and listening techniques to confirm accuracy.
  2. Tuning the Ding (Central Note): The ding is the largest and most prominent note, typically positioned at the center of the handpan.
  3. Balancing the Tones: The artisan ensures that all notes are in harmony with each other, creating a cohesive and resonant scale.

Since handpans are sensitive instruments, even minor adjustments can impact the overall sound, making the tuning process time-consuming and highly intricate.

6. Bonding the Shells Together

After tuning, the upper shell and lower shell are joined to form the complete instrument.

  • The two halves are glued together using high-strength adhesives or welded in some cases.
  • The lower shell features a sound hole (gu), which allows air to move and amplifies the sound.

This stage must be done carefully to avoid damaging the tuning achieved earlier.

7. Fine-Tuning and Testing

Once the shells are bonded, the handpan undergoes a final round of tuning and quality control.

  • Fine-Tuning: Small hammer adjustments are made to refine the notes and harmonics.
  • Sound Testing: The instrument is tested for:
    • Pitch accuracy
    • Sustain (how long the note rings)
    • Tone balance across all fields

The artisan plays the handpan to ensure it delivers the desired scale, tonal clarity, and resonance.

8. Finishing and Polishing

To complete the process, the handpan undergoes finishing touches to enhance its durability and aesthetic appeal.

  • Polishing: The surface is polished to achieve a clean, smooth look. Some handpans have matte finishes, while others have a shinier surface.
  • Protective Coating: A protective oil or lacquer may be applied to prevent rust, particularly for nitrided steel handpans.

9. Final Inspection

The finished handpan is inspected for:

  • Tuning accuracy
  • Structural stability
  • Visual imperfections

Only after passing these rigorous checks is the handpan considered ready for use.

Key Considerations in Handpan Making

  • Skill and Experience: Crafting a handpan requires years of practice. Handpan makers, often called tuners or artisans, spend countless hours perfecting their technique.
  • Handmade Precision: Since most handpans are handmade, no two instruments are exactly alike. Each one has its own unique personality and sound.
  • Scales: Handpans are tuned to specific musical scales, such as D minor, Celtic, or Hijaz. The chosen scale defines the instrument’s emotional and melodic range.

Conclusion

The creation of a handpan is a remarkable blend of art and science. From selecting high-quality steel to carefully hammering each note into existence, every stage of the process requires patience, precision, and passion. The end result is a beautiful, resonant instrument capable of producing rich, meditative sounds that captivate musicians and listeners alike.

Whether crafted by seasoned artisans or innovative newcomers, each handpan is a testament to the craftsmanship and musical ingenuity that goes into its making.
