The piano has been in it’s current form for over 150 years. It has been in development for over 300 years. It has a lineage that can be traced to the 3rd century BC through its keyboard cousins including the organ.
Beethoven, Mozart, Liszt, Ellington, Chopin, Tatum and Melnyk; it has been the primary musical tool of some of the greatest musicians the world has ever known. Its hugely important in an almost endless list of styles and forms of music. Its warm, wood tones are inspiring to the composer as well as the listener.
It’s weakness in the modern world is a lack of portability. This contributed to the ascendancy of the guitar which is now arguably the single most important instrument in worlds current musical landscape. Unfortunately, no true facsimile exists that accurately mimics the both the feel and sound of the piano despite the hundreds of pieces of hardware and software dedicated to doing so.
