Inharmonicity

<<    Greetings, 
 Inharmonicity is, literally, the lack of harmonicity.  In the tuning venue,
it
 refers to the fact that partials produced by piano wire are not exact
interger
 multiples of the fundamental frequency, but rather, are higher values. 
     An ideal string, with no inharmonicity, tuned to 100 Hz  would produce
its
 second partial at 200 Hz.  However, a real string will exhibit a second
 partial of 200 + something. This is inharmonicity.  
    When tuning an octave, by attempting to match the fundamental of the upper
 note to the second partial of the lower note,  the upper notes fundamental
 will be slightly more than double the Hz of the lower fundamental, since the
 lower note's partial is increased due to the inharmonicity.  
 Hope this helps.

And some people think piano tuning is easy. What is so scary, is that I know
what Ed is talking about, and it is still confusing. :)
