We had talked about these before in MMD, I think.  Faventia barrel
pianos are basically a toy version of the old street pianos.  They do
not hold their tuning -- period!  You can tune whatever note is way out
of tune, but generally it is best to leave it alone, as that is simply
how they sound.

Do not put a great effort into perfectly tuning it; that effort will
be nullified within hours after.  The soundboard is not that from
a Steinway piano -- it will not stay in shape.  Just get the tunes to
be recognizable and appreciate that you were able to do as much.

I've played these in my youth around various rallies across Europe; no
tuning that I can recall, except maybe one of the pins having loosened
right out.
