oops, this answer is not complete.
Defining a markup command will make it possible to write eg:

  c1^\markup \change Englischhorn"

which may be still too verbose.

Less verbose would be a music command expanding from:
  \changeInstrument "Englischhorn" c1
to:
  << c1 s4*0^\markup \bold \box "Englischhorn" >>
