I wouldn't say that the 1st partial on unichords (A0-A1) is completely useless. Even though its energy is low I have for the past several years been tuning the notes within that octave using the 1st partial of the lower note in any given octave against the subtone, undertone, resultant tone, ghost tone, difference tone (or whatever some may call it) of the upper note/lower note of that given octave.
Example:
Upper note is X1
Lower note is X0
Resultant tone is Xr
X1=102Hz 1st partial
X0=50Hz 1st partial
X1-X0=Xr
102-50=52
Xr-X0=audible and tactile beats
52-50=2bps
In this instance I'd raise the pitch of X0 to 51Hz to get
X1-X0=Xr
102-51=51
Xr-X0=audible and tactile beats
51-51=0bps
I'll do this even if the higher partials fall out of alignment a little.

Hi Cobrun,
For all practical purposes there is no fundamental on pianos below about A1. To clarify, the energy in the 1st partial below about A1 is so small that it can't be detected consistently or recorded accurately. The human ear fills in the fundamental at A0, but it's really not there. For those reasons Pianalyzer doesn't show fundamental below A1.
On the plus side, the fundamental in the low end of the piano is useless for tuning since there are no coincidental partials for the fundamental. :)
Best regards,

Hello folks,
Sorry I didn't realize Cybertuner had this...the more you know. Thanks Dean, I will start using this feature, however is there a way to pinpoint the 1st partial on A0-A1 inside or outside of Cybertuner?
Thank you.
