I did a quick search and did not turn up a post related to deliberately playing left-handed. I found references to some with disabled right hands playing left-handed and even left-handed people who play right-handed but yearn for a left-handed trumpet. My question is, why is it not acceptable to just play left handed? After all, most Flugelhorns have the bell pipe on the right and the right-handed players must put their hand over the pipe. So, why could a left-handed person not learn to play left-handed on a trumpet/cornet the same way? I have a grandson who is left-handed. He continues to try and play left-handed. I have not discouraged him because I can still remember when left-handed people were almost forced to write with their right-hands to "break" them of left-handedness. So, I have just let him go (he is only 6 and just goofs around so he has not developed any real pattern yet). I see other instruments - such as guitars - designed for left-handers. Why not play a trumpet that way?
