tuning two pianos together

[David Love]

Just tune both pianos to their best optimum tuning paying special attention
that your A3 and A4's are a match.  If you are using an ETD fudge the treble
settings so that they are slightly closer together.  The two pianos in
question will have somewhat different stretch numbers at the upper end so
lower the higher one just slightly and raise the lower one.  They don't need
to be equal, just closer.  If they are close enough then only the last
octave will have any appreciable difference.  No matter what you do,
something will be compromised, however, since two piano works rarely play in
unison, it probably won't be a problem.
