Pitch in Paris ca. 1860

[Stéphane Collin]

Apparently not :

If we agree that flexibility is the ability of some stuff to change its 
shape easily, and elasticity is the ability of some stuff to recover it's 
original shape after having been altered, then for a string, more tension 
increases elasticity and decreases flexibility, and lowers the 
inharmonicity.  I believe that more tension in the string reduces somewhat 
the internal frictions, which I believe are responsible for the 
inharmonicity.  Not sure of that, though.  But I believe that in a 
soundboard, it is the same, but with more pressure instead of tension.  More 
compression in a board, less internal frictions, and better tone.

Best regards.

Stéphane Collin.
