When I first learned to play guitar (ahem, about 40 years ago), due to small hands I learned to finger a G with my 1-2-3 fingers. Never a problem - yes, it takes a second longer to switch to a C or F, but it was pretty much automatic.
I've decided to start playing again and am trying to learn from scratch. So as I go to form a G, I'm trying to be good and use 2-3-4. But a) it's hard; b) it does not sound right - I'm muting the 5th string with my 3rd finger (remember the small hand thing).
When I try to practice chord changes, if I don't look at my hands I notice that I'm back to the "old" G (1-2-3).
It seems like I should have the basics of Chord formation done right for the long term. But with small mitts and original habits, it's hard.
Any advice/opinion on a) how to unlearn the habit; or b) if I should just stick with 40 year old muscle memory?
