Sinking refers to a crucial technique in the construction and tuning of steel pans, where the surface of the pan is intentionally depressed or 'sunk' at specific areas to create distinct musical notes. This process allows for the formation of various pitches by manipulating the metal surface's tension and shape, which is essential for achieving the desired sound quality. The precise sinking technique affects not only pitch but also harmonics and resonance, making it a foundational aspect of steel pan craftsmanship.
