Going to try and distil this down to one question!
My 9yo daughter is interested in music, and and at the moment rock guitar. We have loads of guitars and ukes around from me and her mum playing so she likes to just pick up and twang. She is very very independent minded and against formal instruction - this is fine by me; I was very put off the violin by the formal lessons and learned guitar on my own, I'm quite happy for her to do that and give her pointers (if she'll let me, however that's a whole other story).
However, despite being right handed for everything else, she always picks up the instruments lefthandedly. I have suggested she just try and get used to the other way round, just for ease of access to instruments, and so it's a bit easier for me to teach her if she wants that, but she insists that it feels weird and she can't do it.
I don't know how much of this is 9yo stubbornness (she is Strong Willed to a fault) and how much is kind of biology? It feels to me that right at the start both hands don't know what to do so it should be just a case of learning one way round? But obviously I just started and continued right handed.
So I suppose the question is, to ideally anyone with experience themselves or teachers, can right-handers just naturally be left-handed for the guitar, and should I just accept this and retune a uke, or should I keep trying to encourage her to try playing right-handed?
