Comments by pianists using reduced size keyboards come from various sources including published papers and a growing body of anecdotal evidence over the last two decades.
There is a great deal of consistency among the comments about the benefits of smaller keyboards. Actual hand size and shape, however, would most likely influence pianists’ reactions. For a pianist with extremely small hands, the expanded repertoire suddenly available and ability to play octaves and large chords far more comfortably, are among the most dramatic changes.

Survey of pianists published in 2012
Rhonda Boyle (2012) conducted a survey of 22 pianists who play, or have played, reduced size keyboards in North America and Australia. The results were consistent with comments previously recorded by Carol Leone, Chris Donison and others. Respondents reported improvement with many of the 22 skills listed. They were most likely to report ‘dramatic’ or ‘considerable’ improvement with:-
- ability to hold down notes as intended
- feeling of power where needed
- fast passages of octaves or large chords
- time taken to master technically difficult passages.
Other skills for which more than 50% of those who responded rated the perceived degree of improvement as ‘considerable’ or ‘dramatic’ were:
- legato playing
- broken octaves
- broken chords/arpeggios
- changes of hand position
- time taken to learn new repertoire
- awkward or non-ideal fingering
- overall feeling of security
This survey did not find any significant difference in perceived improvements among the group with the smallest hands (<7.5 inches) compared to those with slightly larger hands (between 7.5 and 8 inches).
For a pianist with a hand span closer to the average for females, changes may be more subtle, such as the improved legato playing, musical line and phrasing and reduced tension when playing octaves. This group of pianists, who can pay a 10th for the first time, also find that are able to tackle repertoire normally the preserve of male pianists, such as works by Rachmaninoff and other Russian composers, Ravel, and advanced Chopin or Liszt works requiring larger spans to play effectively.
The other pages under Pianist Feedback describe these improvements in more detail.
Feedback from conferences and other events
A Walter upright piano with DS5.5® (7/8) keyboard was available at the 2011 Australasian Piano Pedagogy Conference for delegates to try. Those who played long enough to feel sufficiently comfortable with this size found certain skills to be easier. Pianists who reacted positively included males with hand spans of more than 8 inches (20 cm). ‘Octave passages’ and ‘balance and voicing’ were most commonly noted as being easier. At the 2013 and 2015 Australasian Piano Pedagogy Conferences, and the 2016 EPTA conference in Reykjavik, a Kawai GM12 grand piano with 15/16 (6.05 inch octave) keyboard was available. Delegates trying it found that the time needed to adjust from the conventional keyboard was minimal.
At the 2015 APPCA conference, six of Melbourne’s top professional pianists took part in a recital and panel discussion using the Kawai GM12. Their hand spans ranged from 7.1 to 9.2 inches and they had all had very little practice time on the smaller sized keys. For the pieces they chose, ALL pianists discovered advantages when playing the 15/16 keyboard. For those with the smallest spans, the benefits were profound and wide-reaching, while for those males with the largest hands, they found larger intervals (9ths and 10ths) much easier, as well as voicing of large chords such as in a Rachmaninoff Etude. This experience suggests that keyboards with narrower keys would benefit a very large majority of pianists at least for some repertoire – including even those with spans of more than 9 inches! It also indicates that repertoire written by some very large-handed male composers – Rachmaninoff, Vine, Grainger, Liszt – is inaccessible to many. Even male pianists with ‘average’ hands are able to perform some of their works more successfully on a keyboard with narrower keys.
A similar recital by four distinguished pianists/pedagogues in the US was held at the NCKP conference in Chicago in 2017.
There have been many other events in the USA and Canada where pianists have had the opportunity to try alternatively sized keyboards. Some of these are mentioned here: http://paskpiano.org/performances-and-conferences/
Literature covering tips for small-handed pianists
Looking at the issue from the perspective of a small-handed pianist, there is a wealth of information available about how to ‘adapt’ to a keyboard that is too big. Some of the tips promoted by so-called ‘experts’ are not evidence-based, give false hope to many, and may even be harmful.
Although its focus is not about alternatively sized keyboards as such, an excellent book has recetly been published by Oxford University Press: Adaptive Strategies for Small-Handed Pianists (Deahl & Wristen, 2017). It provides a great summary of the many ‘work-around’ strategies that small-handed pianists need to adopt and gives the clear message that the issues are not trivial. The title does not totally convey the breadth of what is covered – the introductory chapters deal with the evolution of the piano and piano repertoire, anatomy and biomechanical principles relevant to piano playing, the wide-ranging problems of small-handed pianists and common maladaptive tendencies.
