I'm left-handed but not as much as some. I write with my left hand, pretty much everything else I do right handed
That's pretty much the same for me I've also noticed that the right hand becomes tired faster. How difficult repertoire are you playing Leah? Do you think being left-handed has hindered your progress?
edit: And for the record, the fact that left-handed pianos are not very common (like similiar quitars), I have come to believe that being left-handed is not that much of a disadvantage.
