‘We have encountered many gifted students with small hands who have had to overcome great difficulties when playing standard-sized keyboards. Their special needs frequently are ignored, misunderstood or underestimated by teachers who have never had to personally grapple with issues of hand size.’
Dr Lora Deahl, Texas Tech University, & Dr Brenda Wristen, University of Nebraska-Lincoln, USA, 2003.
