I did an experiment on a bassoon recently, I painted it! In the beginning of the quarantine I bought a plastic tenoroon from China, it plays well for what it is. I thought I would use it more in arrangements but then it would make the arrangement less accessible for people without a mini bassoon.
I painted it with a matte lilac spray paint and it came out great, so I decided to do my Linton bassoon also. My Linton sits in my closet now that I don’t teach, and I use it for outdoor evening gigs. For the Linton I used a darker lilac satin spray paint and the resulting finish has a bit more shine to it.
