Phil Tompkins stated that he had dyskinesia when concentrating on notes while playing the piano. I guess everyone is different, but I am reminded of a female artist who could "paint" without problem but had tremors at other times. As a piano teacher, I am wondering if playing pieces you know well, the kind you don't have to really concentrate on any more--maybe something at a moderate tempo (which is easier than slow or fast) might give a different result. If you try this, please let us know. Carol Horner
