Apparently over the last several hundred years there have been very few changes made to ‘The Piano’ (after it’s transformation from the harpsichord) A recent and radical departure from the traditional piano has occurred right here in Australia by the piano makers Stuart and Sons. Basically the way the strings are wired has been changed, a fourth pedal added and a number of keys added. (from the traditional 88 to either 93 or 102!) The website for Stuart and Sons is below. I recommend the drop down menu ‘The Sound.’ From there check out Players Comments and Video Clips. Very intriguing! Is this the future of the piano?
