PASK (Pianists for Alternatively Sized Keyboards) has produced three videos that summarise the case for keyboard choice: Part 1 is an overview of the issues, Part 2 describes the experiences and shows performance extracts of pianists who play smaller keyboards, and Part 3 is a summary of the statistics on hand spans, including gender and ethnic differences, and why hand span is important for piano playing. There are also versions with Japanese and Chinese text:

The first pianist to ever play on an keyboard with narrower keys in a piano competition was Artem Arutyunyan in the Dallas International Piano Competition, held in Dallas, Texas in March 2014.  Steinbuhler DS6.0® and DS5.5® keyboards are available as an option for contestants entering this competition. Artem chose the DS5.5® inch keyboard and adapted to this size after only a few days of practice!  See a brief excerpt from his performance: and also a video showing how quickly the keyboard can be being changed during a competition.

At the same competition in March 2015, Artem performed once again, this time on a DS6.0® keyboard. Another contestant, Anna Arazi, won third prize using a DS6.0® keyboard. She had never played this keyboard prior to the competition and adjusted completely after just one day of practice. The pain she had been experiencing previously in her arm completely disappeared. See this recording of Anna’s first round performance of Prokofiev’s Piano Concerto no 1:
