I've coming back after ~10 years off as I've mentioned in a few other posts and am desperate to do things right from the get go rather than fix bad habits after they've been ingrained in my muscles.
That being said, I was doing some practicing (simple tunes after some Clarke) and got to focusing on how I tongue. I realized I don't use the "too" or "doo", where my tongue would hit near where the back of my top teeth and gums meet, as many people say you should. Instead I tongue by putting my tongue into the space my lips make sort of like a plug.
I'm pretty sure this is how I've always done it since muscle memory took over after picking the horn back up from my hiatus.
My question is: Would it be worthwhile to work on a "proper" tonguing technique while I'm building up my endurance and other skills or is my current technique something that wont be detrimental to future playing?
