I remember a few years back I made a post here about a box I would play into to reduce the sound to stop annoying my family lol. But I would think if you have an extra mouth piece you can sacrifice, plug the hole with cotton or paper and use your Pianica as a silent instrument. I can’t remember when, but we also came up with a minor solution which was to plug the mouthpiece hole with something hard enough that you can drill a small hole and this will reduce the volume that will come out of the Pianica. You need to start with a very small hole and work your way up to a larger hole until it sounds. Note some reeds will not sound due to the amount of air needed, but you can hear some of the reeds to give you an idea of what you are playing
