The conventional piano that we all know and love measures in at 6.5 inches to the octave. Donison-Steinbuhler piano keyboards (The DS Standard) produced by Steinbuhler & Co. offer multiple key widths:

As of 2020, Steinbuhler & Co. is the only company in the United States manufacturing reduced-size keys. Pinkham Pianos in the UK also builds them to order, along with a number of interesting developments including “dummy” practice keyboards and magnetic balance action.


Research on the ergonomics of piano playing is slowly expanding, including the effects of large keys on small hands.


Chair of the Department of Piano Studies at SMU, Dr. Carol Leone is a pioneer in the effort to standardize multiple key widths. Besides her own trailblazing work with these keyboards, students at the university have the option of working with DS6.5, DS6.0, and DS5.5 keyboards. Additionally, the Dallas International Piano Competition held at SMU is the first to offer multiple keyboard sizes to its contestants.

Information about conferences, performances, and competitions is available on the PASK Piano website, as well as how to locate a DS keyboard near you.

Any pianist in the West Palm Beach area wanting to try out a 7/8 is welcome in my home.
