- Do pianos evolve? They do ! Pianos have been evolving since their invention 300 years ago. The Piano was conceived from the desire and need for innovation resulting in the redesign of the action mechanism of early keyboard instruments allowing the instrument to create soft or loud tones. This revolutionary concept gave birth to the pianoforte, the ancestor of the modern piano.
The following pictures show the major changes in piano actions from the Cristofori’s mechanism to present day:
1726 Cristofori’s Piano-Forte mechanism: This was an innovating mechanism which allowed a keyboard-instrument to be played soft or loud leading to what we know today as the “piano”
1808 Erard’s piano action mechanism. This design was a major leap in action mechanisms sophistication and performance. All modern designs are based on this concept.
1931 The American Steinway piano action. An improved design to the action of the piano. This action has remained unchanged and it is used in present Steinway’s pianos.
2000 The modern German made Renner action. Currently used in German made Steinways and other brands.
The Millenium III high performance piano action mechanism used in Shigeru Kawai Pianos. Note the wood precision components used in older actions have been replaced with carbon fiber composite materials. These components are not affected by heath, dryness or humidity. Resulting in a very stable precise mechanism.
