Quickie Pitch Raise

[Cy Shuster]

OK, Terry, I've misunderstood your approach.   In the first pass, you
overpull one string of a bi- or trichord by the same amount it's flat?  (Or
half as much, for bichords?)  The math makes sense that way.  I can see why
you'd limit this to small pitch corrections, though...
