You can set the region manually and then use
a function with

    (goto-char START)
    (while (re-search-forward REGEXP STOP t)
      (replace-match TO-STRING nil nil))

where START is (region-beginning) and STOP is
(region-end). First check if there is a region
with (use-region-p) !

Or if you want it fully automated make a search
for "\startpiece" and set START, then make
a search for "\Endpiece" and set STOP. Do this
in Elisp as well.

But then you'd have to supply them (the
delimitators) as arguments so it won't
necessarily be faster because you'd have to
type them each time rather than to set
the region.

If they (the delimitators) are always the same
you could hard-code them, of course. Then it'll
be very fast to invoke :)
