I'd never even heard of this instrument before. Amazing. Thanks for sharing it. I'm curious about the dynamics of the Stick. In some ways it reminds me of the difference between a harpsichord and a piano -- the piano was originally called "pianoforte" because it could play soft and loud. It does seem a talented player can introduce some dynamic variation. I wonder if the Railboard allows for greater dynamic range. Regardless, what an incredible, unique sound!
