Phasing/fazing

I think what Roger was referring to was that if strings are not level, (or hammers not mated to strings properly) that the individual strings of a unison will be struck at slightly different times, resulting in the vibrations of those strings being slightly "out of phase" with one another.  That is, the strings start making their noise at slightly different times.

Picture a sine curve (for example).  Now picture three sine curves perfectly on top of one another.  That would be the three strings of the unison "in phase" with each other.  Now take one or more of these curves and shift it slightly left or right.  That curve is now "out of phase" with the others.  Creates all kinds of voicing issues - weak sounds, false sounds, etc.

  Roger used the term phasing on a few occasions mostly when talking about voicing and strings.
