This website has been developed by Rhonda Boyle, of Melbourne, Australia. She was  the first person to import, from North America, a DS5.5®keyboard for her grand piano. Its purpose is to raise awareness of significant problems relating to the ‘one size fits all’ approach to the piano keyboard. 

Rhonda was listed in the Australian Financial Review’s 100 Women of Influence for 2019.

Rhonda Boyle’s research papers can be found here:

A bibiography is available here:

The website presents a solid body of evidence of the need for a choice of keyboard size (specifically narrower keys, not fewer keys). This evidence includes:

  • the historical basis of today’s conventional keyboard which suits ‘large’ hands,
  • a summary of relevant research covering pain and injury among pianists,
  • statistical information on the hand spans of pianists generally and how hand span is relevant to piano playing,
  • results of piano competitions, and,
  • stories from pianists themselves. 

The ultimate goal of the PASK (Pianists for Alternatively Sized Keyboards) movement is for the major piano and keyboard manufacturers to provide a choice of keyboard size in new pianos sold throughout the world.

To learn more about the PASK campaign, including information about events, media stories, manufacturers, and where you can try keyboards with narrower keys, please visit:

The information presented here is intended to assist pianists, parents and teachers lobby for change in their own parts of the world.

Rhonda has no financial connections with any piano or keyboard manufacturers. She is a director of the non-profit DS Standard Foundation:
