Whether your instrument was drawn, hammer sunk, hydro formed, spun, or rolled will have an impact on the tuning techniques implemented.  Having tuned instruments upon most of these platforms, attending numerous festivals, as well as having instruments shipped to me from around the world, I have tuned handpans made from all of these methods and continue to expand my understanding of how these differences inform which approach to undertake.  For every handpan repair or handpan tuning that comes into the shop I make a before and after video.  Below are some videos of work I have done on instruments from various handpan builders.  This page will be updated regularly as new Hang and handpan drum repairs and tuning arrive.
