Left handed playing
General mountain dulcimer or music discussions
@kristinrichmond, you've received good advice so far. The first thing to figure out is if your daughter wants to play lefty. Have her play a little right-handed for a spell and then flip the dulcimer around and have her play left-handed. See which way she feels most comfortable. Some lefties play right-handed with no problem. Both hands are involved, after all. But others find that the strumming or picking hand should be the strong hand.
If it turns out your daughter does want to play lefty, then you can just reverse the bass and melody strings, although as Noah and Ken explain, the melody string might buzz a little bit. There are some ways to "MacGyver" that issue short of getting a new nut and bridge, so if that's an issue chime in here again.
I wouldn't bother putting on a new nut and bridge until you determine that your daughter really wants to play lefty, that the strings are buzzing or the intonation is off, and that she is going to stick with it for a while. And if that's the case, perhaps her grandfather
will buy her an instrument build for lefties and you won't have to lift a finger!
By the way, that old man smiley is an exact portrait of @sam, isn't it?
