About EchoSoundSculpture
EchoSoundSculpture is a handpan/pantam studio in Switzerland that has been building instruments since 2009. The handpans are not produced on an assembly line; instead, every instrument is crafted by hand, tuned and finally commissioned. The shells are pressed and treated by Swiss suppliers. The studio is best known for the AsaChan instrument series, including the mini handpan AsaChan MiRim with a 46 cm diameter. Since 2023, Flavio Brant Alvim has been the sole handpan maker and works with the musicians Damien Vielle and Drui Glueck Schmid. Personal customer contact takes place on site or by e-mail worldwide.
