That sounds a bit crude. The complexity of the innards of a piano used to
fascinate me. Obviously its not just one string for each note which is
tuned, but I never did get into the way it was all supposed to work.

It says here, it has to be restored, before it can be tuned.

Makes for a cheap instrument :-) Replacing
all the strings, dampers, and degrade-able materials.
I guess you get to keep the original wood.

You could keep the strings and the "untuneable nature",
if you had one of these autotuners. Average operating
power = 800W to keep the piano in precise tune. The
800W represents the amount of heat needed to pull the
piano from initial tuning state, into tune.

So rather than rotate a peg to tune the string,
it uses electricity and heat in the string, to
set the frequency.
