Willi Corall from Siefersheim crafts unique hook harps, dedicating 80 to 120 hours to each instrument. His passion for instrument-making began in childhood, and he specializes in creating harps that offer adjustable pitch, a feature introduced in the 18th century. Corall prefers using local woods, stored under a walnut tree in his garden, which give each harp its unique color and grain. It takes him seven years to carve parts from wild cherry wood, and he sources high-quality spruce from Mittenwald for the soundboards. For Corall, his work is not just craftsmanship but a deep dialogue with the materials, blending passion, humility, and devotion.
