[CAUT] ghost tuning

[David Love]

If you're testing a 6:3 octave (for example) then you would hold down C1 and
C2 so that the dampers are lifted off the strings but the hammers don't
actually strike the strings.  Hold down mute, it's called, and then strike
(not hold down), strike and let go of the G3.  Striking G3 will excite the
6th partial of C1 and the 3rd partial of C2 in isolation.  You then can
listen for the beats that form between that particular coincident partial
without the confusion of the other partials.  If you are tuning a pure 6:3
octave then you manipulate the lower note (presumably) until it is beatless.

Please explain a little more. What am I listening for when I hold down the
two bass notes, and what interval are you using? If I hold down C1 & C2,
what other note should I play, and what should I hear?

Hold down two bass notes (an octave apart) and strike the note the
corresponds to the coincident harmonic that you want to use as the test
partial.

Some time ago a tuner told me about ghost tuning the bass. I tried it a
couple of times, but I've not used it for a long time, and forgot how it's
done. From what I remember, you hold down a bass note, and listen to a
partial an octave and third up, or the other way around. Does anyone know
about this?
