So yes they would sound terrible it played together. In your case you would have to tune your guitar to A-432hz.

Actually my wife's old upright piano is tuned to A-432hz to reduce the tension on those old parts; I mean the parts of the piano and not the wife grin.


Thank you. Then there's no way a jaw harp (using 440hz) is going to gel with a tongue drum tuned to 432 hz. Ugghhh.
