Una Corda Blues

Hi Alan,
                  I dislike the term una corda, but alas we are stuck with it.
Shift pedal would better describe it. since in todays use, it is primarily 
used to shift the colour of tone. ( move to a softer part of the hammer)
On a well regulated grand, it should be able to play the softest of ppp, 
with out the aid of a pedal.
If you have to make a choice between left and right hand, go with the right 
since that is where most tunes are played.

Yes

The first string just misses by a hair. this will give max range for half 
peddling.

It's quite acceptable to have the bottom string just clipping on the bi chords.

If you have to really move the bass hammers to align to strings, remember 
to realign the wippens.  There is a good diagram in our interactive 
regulation series to show how all the components align, and how to adjust 
each part.
