The Acoustic piano as a laboratory of science
Hello, This work was done for the glory of God and His son Jesus Christ. Subject resume: The main and more complete polyphonic instrument of the symphonic orchestra is the piano-forte. An italian invention of XVIII century today it appears to the scientific community as a wide laboratory where is possible to apply, find, and verify many principles of acoustic physics and correlated disciplines in deep way.
The evolution of piano transformation has been lasting for over 200 years, in many cultural atmospheres some people think therefore that the mechanical operation and essential acoustics of the instrument must be considered something not more permissible to improve, a kind of nineteenth-century technology masterpiece; all of that is now debatable from
the technological progress of the last decades, and from the multimedia development
however.
An essential aspect of piano functionement has been examined here since in the instrument converge many specific technical specialties.
The search on the expressive possibilities and operation mode of the piano is multiple, for instance software of acoustic simulation for digital synthesis, electronic and electroacoustic robotics for keyboards, ceramic acoustic actuators, studies on the physical qualities of new materials like carbon fibers, kevlar, etc.
Beside all that, specialized procedures for manufacturing traditional materials to produce high quality spare parts for acoustic pianos are in constant development.
This website focus principal excerpts of a graduate physics thesis on a model of pianoforte mechanical functionement, a theoretical compendium but also practical was wanted to be realized in this work, considering previous physical models that describe the way in which works the conventional acoustic piano playing mechanism. Has been attempted to give importance to many of the phenomenological aspects of the action that still have not been sufficiently studied and experimented in such models, a new model is proposed and discussed.
If in the accomplishment of this task the more remarkable aspects have been visited, and this could somehow stimulate curiosity nor perplexity of readers of scientific literature and artists, the author could consider himself lucky.
