Re: different sizes for instrument names (Staff vs. PianoStaff)

[Mats Bengtsson]

The simple explanation is that the fontSize property is handled by the 
Font_size_engraver, which by default lives in the Staff context. Since 
the PianoStaff instrument names are typeset at the PianoStaff level, it 
means that the value of fontSize isn't used, then.
One solution is to add the engraver also at the PianoStaff level:
\layout{
 \context{
   \PianoStaff
   \consists "Font_size_engraver"
 }
}

As far as I can see, this does not influence how the fontSize property 
is handled at the Staff level, so there should be no negative side-effects.

An alternative, is to explicitly set the font size for the instrument names:
\new PianoStaff \with { \override InstrumentName #'font-size = 
#(magnification->font-size 2/3) ... }
