When it comes to pianos… size matters!  Bigger is ALWAYS better.  In pianos there are four areas where size comes into play: the soundboard, the hammers and shanks, the strings and the keystick.  All of these four areas contribute to a piano sounding as rich as possible and feeling as consistent as they can be.  The soundboard is the amplifier to the piano.  The more square inches of soundboard, the greater the resonating area (if it’s manufactured correctly).  The longer the stings on a piano (which means either length in a grand or height in an upright), the deeper the voice of the piano.  The longer the shank (within reason), the better the blow distance of the hammer to the string (and also less of an arc is required).  And finally, the longer the keystick, the greater the control.  That is why taller uprights are considered ‘professional’ and semi-concert grands and concert grands are 7 and 9 feet long… Bigger is ALWAYS better.

Pictured are two pianos – the one above  is a small upright piano.  The one below is a tall professional instrument.  Note that the size of the ‘action’ – the mechanism is considerably taller in one than the other.  This provides better control over the keys – especially in the area of quiet playing.
