With the price for new musical instruments skyrocketing, it’s not surprising that some people have actually gone into building their own instrument! Most of the people I have found who built their own horns don’t actually play but are master carpenters or handymen who are curious. Others are musicians who are testing out different possibilities of their instrument families.
This man made a wooden trumpet out of a home workshop. Although he isn’t a trumpet player, this is a functional piston trumpet.
The Bamboo Sax has been around for a while, I saw one on vacation in 2006
The least embarrassing bassoon related video I could find was of Robin Howell making a bassoon bocal, which would be interesting to try but I don’t think I would trust it!
MY favorite video on youtube right now is of this guy who built his own CONTRABASSOON! It actually sounds nice, has a recognizable scale, and doesn’t look like garbage. I was really amazed when I saw this.
