One of Vladimir de Pachmann's favorite tricks before a recital was to play about with the piano stool, adjusting and readjusting it, until the audience became desperate. Then he would rush into the wings to fetch a large book, place it on the seat, and try that. He would indicate that all was still not satisfactory and would tear one page from the book and try again.
