You can adapt quickly!
For the increasing number of pianists who play alternatively sized keyboards, their is overwhelming evidence that practically everyone can adapt to an alternative size very quickly.
Adapting to the DS6.0 size (6.0 inch octave) is almost instantaneous, while adapting to the DS5.5 size (5.5 inch octave) generally takes less than an hour. Pianists then have no trouble going back and forth between different sizes.
While some fear that they would lose their ability to play the conventional (6.5 inch octave) keyboard, this does not happen. On the contrary, pianists report that they actually improve their playing when they do have to play the conventional keyboard again, having developed a more relaxed technique on narrower keys.
Because no-one alive today was around when different keyboards were available prior to the 1880s, pianists are often unaware of our flexibility regarding keyboard size. It’s a bit like climbing stairs of different sizes – our brain copes with this task automatically.
