At the same conference, six well-known Melbourne pianists performed on a Kawai GM12 150 cm grand piano with octave size a little over 6 inches (approx 15/16 of the conventional size). These pianists all chose repertoire they found challenging or uncomfortable on the conventional keyboard, and they had very little preparation time on the different keyboard size. In the panel discussion afterwards, they spoke very positively about the benefits of this keyboard.  The hand spans of these six pianists covered a wide range – from a woman with very small hands to three men with ‘average’ size spans for males.  As one of the participants, a successful teacher of elite young people, Glenn Riddle, said afterwards: ‘These pianos should be everywhere!’
