I attempted to learn two languages before learning the saxophone. It was an incredible effort done almost entirely academic. I could read and write and speak plenty however it was like machine often working incredibly slowly, in particular for sentence formation. When I learned the saxophone I realized how similar learning an instrument and language are. Really they are exactly the same. You’re ear training for sound. Learning sound phrases. I learned you learn by practicing it and I’m absolutely sure learning a language is the same. You don’t learn an instrument academically although it does set the foundation for actually learning it through practice. I have now had a near 1.5 year break from playing the saxophone after getting very good at it for two years. After getting back into it you’d think I’d be rusty. Although I’ve forgotten memorized songs my ability to play after just a few sessions of tarnish polishing has put me in a place questionably better than I left off. Just stick to live real practicing of the language and try to move from needing to be perfect and practicing with people who won’t practice with you unless you’re perfect. Get some raggedy people to practice with.
