CyberGene ChatGPT wrote: The pivot length, also known as the key length or key lever length, is an important factor in piano design. It refers to the distance from the front of the key to the center of rotation, where the key pivots. The pivot length affects the leverage and feel of the keys.
Generally, longer pivot lengths provide greater leverage, resulting in a lighter touch and increased control over dynamic expression. This is because longer pivot lengths allow for more leverage and require less force to depress the keys. Pianists who prefer a lighter touch may prefer pianos with longer pivot lengths.
On the other hand, shorter pivot lengths can offer a faster key response and a more percussive touch. Pianos with shorter pivot lengths may require more finger strength to achieve the desired volume or dynamic range.
It's important to note that the pivot length is just one aspect of piano design, and the overall construction, including the key weighting, action mechanism, and quality of materials, also play significant roles in the touch and feel of a piano.
Ultimately, the ideal pivot length is subjective and depends on individual preferences and playing style. It's recommended to try out different pianos with varying pivot lengths to determine what feels most comfortable and responsive to your playing.
