I played piano, and trumpet.
I'm not coordinated enough to use both hands at the same time. With the trumpet, I only used my right hand.
But tuning a guitar is hard enough as it is, it seems to me. If you change the height of the strings, is it possible you will make it even harder?
I also worry that as my frets wear down, that also might make the guitar harder to tune.
Nah I don't think it will. My frets are worn down. But I have an electric tuner that I clip on the headstock and it picks up vibrations instead of using sound.
Then why use it?
Maybe your truss rod needs to be set up and it goes out of tune. Mine is in tune, also the humidity and heat play a role in it.
It's the rod that goes down the center of the neck. Take it to a shop and ask them if it needs to be set up, it may be way out of whack.
