instrument-name

[David Bobroff]

I want to add instrument names to a score.  I don't want them in the
parts.  The different parts in the score are all eventually defined as
\staffA \staffB etc.

Shouldn't I be able to define something like 

staffAnameA = \context Staff nameA <<
        \property Staff.instrument = "NameA"
        \property Staff.instr = "nA"
        \staffA
>>

?

The above produces a score with an extra staff for each instrument.  One
with the instrument name and nothing but a blank staff, plus the staff
with the music.

Obviously I'm missing something.  Can someone straighten me out?
