Steinbuhler Alternate-Size Keyboards

Through a partnership with Steinbuhler & Company, the Dallas International Piano Competition provides alternate-sized keyboards on request to pianists who wish to use them.

The DIPC acknowledges the Donison-Steinbuhler Standard® as the industry’s definitive categorization of keyboard measurements, which codify the various keyboards that are suited to each hand size. By adopting the DS Standard®, the DIPC ensures that its keyboards conform to the following international standards as established by the Donison-Steinbuhler Foundation.

DS6.5®

The DS6.5® standard (conventional keyboard) is equivalent to what is used on the common concert grand piano today. 99% of the worlds pianos conform to this standard. It has a full octave that spans 6.5 inches, with standard allowable deviations of .04 inches. Therefore, all keyboards that span between 6.46 inches to 6.54 inches meet the DS6.5® standard.

DS6.0®

The DS6.0® standard is the largest intermediate alternate-sized piano keyboard option. It is engineered to accommodate a moderate adult hand size, and has an octave that spans 6.0 inches, with standard allowable deviations of .04 inches. Therefore, all keyboards that span between 5.96 inches to 6.04 inches meet the DS6.0® standard.

DS5.5®

The DS5.5® standard is the middle intermediate alternate-sized piano keyboard option. It is engineered to accommodate a smaller adult hand size, and has an octave that spans 5.54 inches, with standard allowable deviations of .04 inches. Therefore, all keyboards that span between 5.50 inches to 5.58 inches meet the DS5.5® standard.

A smaller DS5.1® is also recognized, but not available for use at the DIPC.

Warm-up and rehearsal pianos, equipped with these smaller keyboards, are also available to all participants. SMU encourages pianists interested in trying various keyboards options to make an appointment to do so by contacting Dr. Carol Leone at cleone@smu.edu. Appointments can be accommodated throughout the year.
