I am lucky enough to have a piano playing missus who uses a Knight,so although I am tone deaf I can relate to how the things leaves notes floating in the air
not unlike my new speakers,although considerably cheaper than my last pair,I can't stop listening to Chopin,the difference is dramatic,the notes do indeed hang in the air
what is this called? is it 'timbre'?
Mine plays a beautifully toned 'K. Kawaii' (vintage 1975/76 before the increase of the thickness of the felt on the hammers - a slightly more brilliant tone).
I've found that the 'reality' of the sound of piano music through my system is highly dependent upon how it was recorded. John Atkinson does a phenomenal job of capturing the sound of a Bösendorfer on Orpheum Masters' (Robert Silverman's) "Beethoven's 32 Piano Sonatas". While the Bösendorfer has a slightly "darker" sound than that of my wife's piano, and the room where the Bösendorfer was recorded a little small for the instrument, there is no question that the CD captures the essence of how the piano really sounds.
"Timbre" to me when speaking of recorded music, is not a word I'd use to describe how a note 'hangs in the air' per se. Timbre, again to me, is more than that: it is the sonic signature of the note - the ability to hear all aspects of a 'note': the attack (the hammer as it strikes the string), the vibration of the piano string combined with its resonance through the soundboard and cabinet of the piano, and finally the natural decay of a true piano note in the context of the space that the piano is being played in. It is a very complicated characteristic of an instrument's sound as there are so many variables that can contribute to 'timbre'. 'Timbre' is one of the most critical aspects of realism in a Hi-fi experience (once again, to me).
In my experience, the dynamics of piano music are better produced by a dynamic loudspeaker. I love what planar and electrostatic speakers do with bowed, soft-attack musical instruments, but they do not get piano music entirely "right" to my ear. My Totem Forests, a simple two-way design, excel at reproducing piano music.
Describing a subjective experience with the written word is a difficult task, but to me a note "hanging in the air" is only one aspect of 'timbre'.
