Wow, I’m THEEE Karl Hedlund now? Wonderful
I don’t think I’ve heard of prepared piano before. Basically transform the instrument into a collection of lots of sounds? I think the easiest way to do this on the shamisen might be to have different materials stuck under the notes on the sao, so that different notes have different sounds. I don’t know, but that feels like the direct translation from the prepared piano.
As for the stealthiness of my video, some kind of rubber sheet, like the thingie under the dou would actually be quite cool. I wonder if the plastic actually amplifies the sound again a bit, considering it being so smooth. However, you need something that is a bit hard and solid if you don’t want to destroy it with your bachi or have it move around.
