Equalizing the width of the white keys
has slightly changed the shape of the keytops:
The tops of the black keys extend slightly further forward
to add leverage and accuracy.
Here it is up close. If you notice, the black keys are angled less.
Haven't you ever had to stretch for a black key? Now you don't have to.
Our black key retrofit kit and a completely retrofitted piano are on EBay:
Gregory Shir model retrofit for black keys
This key top can be set up for almost any piano. The design of the keys corrects the pianist's hand movements and resting positions to prevent Carpal Tunnel Syndrome while improving posture, thus allowing the pianist to practice easier with less discomfort.
*More responsive to touch
*Easier to reach keys
*Easier to play rapid passages
