I'm researching double reed instruments with the hope of crafting my own mizmar and being a bit musical this year. I have no formal music background so this has involved a lot of play as I stumble through the kindling of knowledge and understanding :) Much fun with tubes and loud sounds so far this year.
If you are interested in making your own, the plans I followed are from a Thingiverse project for a printable shawm and can be found here:
