Thank you COMMENTS!! I had really never seen this. Much cheaper than investing in a harpsichord, haha. I think it sounds really dope. Totally gonna do this a lot now!
I think its gonna be hard to come up with something more officiant than thumbtacks to put on the piano hammers. Any ideas? Let me know, I wanna try everything. Vibrations and ebows are up for sure, but more fun stuff like this that are 0 cost would be nice.
