Link #2 shows you a left handed accordion.
Link#3 also shows you a left handed player at the Liberty Theater.
If it's possible you can get in touch with one of them to try a left handed one.
I only know of one person who plays a Cajun style accordion, upside down. Guyland Leday is left-handed and plays it both ways. Ray Landry is left handed and plays a left handed guitar and accordion. I am left-handed and play accordion, bass and guitar, right-handed. I have a friend who is the same way. I was told early on that playing the accordion was no different than playing piano. There are no left-handed pianos. You train each hand to do what it needs to do. Now, admittedly, I am ambidextrous in many ways, but playing an instrument is not one.
Ganey arsement thanks very much for your reply. Yes I play guitar right handed and shoot a gun right handed. And maybe a few other small things. I held the right handed and it just felt funny. Like I wanted to flip it the other way. But also I agree with training your hands. I actually had the chance to attend vermillionville 2 weeks ago. Mr Ray Landry was there. He didn't play much guitar. He had one on a stand. He played Cajun bass. I am going to go right handed accordion. I have time anyway. An accordion not really in budget right now. Too much else going on. Soon though hopefully. Thanks again for your information.
steve riley has been known to play a right handed one upside down and backwards
i think for lessons so the other person can see
or maybe as a party trick
