First you need to uncouple the manuals, turn off all the registers except
the 8 foot register that plucks closest to the tail of the harpsichord
(farthest away from the tuning pins) and tune that register to your ETD.
Then you tune the other registers one by one to the register you tuned
first by setting up either the coupler or register levers so that your
initially tuned register and the one you are tuning pluck at the same
time. Tune them as beatless unisons (or octaves, in the case of a 4 foot
register). If this is a Sperrhakke or Neupert or another of those German
production monstrosities with the 16 foot register, tune that one last
the same way. <br><br>

Tune all the registers the same (well, except for the 4’ if it has one,
which will be tuned an octave higher). If it has the keyboard set
up to do modern pitch and low pitch, be sure the keyboard is set for the
high pitch. If it is in low-pitch position and you tune it to 440
you’ll undoubtedly break a few strings. Other than that, it’s a
pretty straight forward job.<br>

</font><b>I have been asked to tune a double manual harpsichord to A440,
Valloti Temperament.<br>
It is in my ETD, so the temperament should be ok.<br>
I have only tuned a single manual, and that was for a friend, 20 years
ago.<br>
They are stuck, and can't find anyone else.<br>
What is involved in doing a double manual?<br>
I know in an accordion, the different blocks are tuned slightly off the
others, by so many cents.<br>
