Narrow Keyboard Playing - Schmale Klaviatur 5.5!

Young Julian from Bayreuth is presenting Steingraebers Narrow Keyboard!
Within 300 years of piano making keyboards changed regarding the widths of the keys, their weighting and its “key dip”. Today's keyboards have an octave of 6.5 inches = 165.1 mm. In 2022 / 2023 Steingraeber built a new model 122 upright with a 5.5 keyboard for a customer in London with very small hands and high pianistic standards. We also converted an older Steinway grand piano to a keyboard size of 6 inches for the Nuremberg Academy of Music.
Try the difference in Bayreuth!
