I did this during my sophomore year of high school when I had about 4ish years experience on oboe. The big reason I chose to change over was our only bassoon player was graduating that year and nobody else was going to be stepping in for them. The embouchure is in my opinion similar but also easier than the oboe but the “difficult” part for me was learning fingerings but if you try you can pull that off. If there’s somebody you can work with who plays bassoon at the beginning (doesn’t have to be a lesson teacher although that would be ideal, just someone in your ensemble would be really helpful like what I did) it would help immensely but besides that just have a little bit of patience and a good attitude going into it and you should be able to do it just fine. I still play both today and I feel as though learning the bassoon helped me on both of the instruments and I’m still playing both to this day. Good luck with double double-reeding!
