pitch raising the bass

[Newton Hunt]

Hi, Fred, welcome to the net.

The bass does not respond differently than the rest of the piano.  It just does
not change as much.

If you are using a SAT it will calculate the pitch change (up or down) based
upon a 25% return.

With the SAT I pick up a change factor from A1 then tune the entire bass to
that you factor.  Works great.

In the middle section I go up a major third or fourth to pick up my first
compensation factor to tune the first notes.  Afterward I pick up a new factor
every major third.  I do not strip the piano if it is a grand, just use a felt
wedge mute all the way.  If it is a vertical I mute the middle section but pull
it out as I tune to do the unisons as I go.  The only reason I use a strip is
because the stgring spacings are to close and irregular it is too time
consuming to use a felt wedge mute.

Have a nice week and best to the family.
