Steelpan building and tuning: General basics and personal observations
Noah M. Sanderson · The Journal of the Acoustical Society of America · 2023
In this presentation, I will share the steps I use to build and tune steelpans, as well as some insights and observations from my experience as a builder/tuner. Building includes welding, sinking (stretching the steel into a concave surface), note shaping, and steel smoothing. After that, the steelpan is burned and then tuned. Tuning is done using hand hammering and occasional heating. It involves tuning multiple modes of vibration independently in a single note panel, adjusting the timbre, and getting the desired interactions between notes. Oftentimes, the tuning experience and final product is somewhat unpredictable. Small differences in the steel shape can result in large changes to the sound, and operations that will work on one note might not for another. Furthermore, there are many problems that arise from detrimental note-note interactions and note-skirt interactions. All this results in a seemingly mysterious nature to steelpans, requiring a degree of trial and error to get the desired qualities. My hope is that a dialogue between tuners and researchers can strengthen our understanding of the instrument from both viewpoints.
