Piano hammers

<<"If the string is plucked or struck at a node of a mode, then the

corresponding overtone will not be present in the sound. Hence, plucking or

striking the string 1/7th (or 2/7th,..) along the string will remove this

dissonant overtone from the vibration. The hammers in a piano, for example,

are located at a node of the 7th overtone for this very reason.">>

Greetings,
The hammers in a piano hit at various places, depending on the location of
the note in the scale. ie, the top treble hammers are often hitting the
string at 1/16th of its length, the lower hammers often cannot reach more
than 1/8th of the string length. The 7th partial is a rather weak one to
start with, but I don't hear it appearing when the action is moved in or out
from its normal position.
It is also worth noting that the contact point of the hammer is usually
wider than on node's worth, so it is actually covering several "nodes". It
doesn't cancel all of them.

This is rather humorous. So much for "piano tuning lore" as
pontificated by anonymous Internet Websites...
