===Instruments===
David Klavins has built multiple pianos with reduced frames to allow the resonance of the strings to be more direct to the listener.  

==Una Corda==
The Una Corda has one string per note throughout the range of the piano.

Im mixed about featuring these instruments on the wiki, I think the primary more of its relevance is the implications of this kind of experimentation with the model of how a piano looks and works. These instruments have a kind of [[Tonal Maximum]].
