Thanks Werner, this is very good.  I've added targets according to the 
model in your version and it now recompiles only those files that have 
changed--almost.

What I can't figure out how to make it do is recompile a score whose 
\include "notes.ily" file has changed, something that is much more 
likely to happen than the main.ly file.  I've added .ily to the list of 
suffixes, and I added a line saying that the .ly files depend on .ily 
files, but when I touch a .ily file, and the pdf for that part already 
exists, it still says "nothing to be done for <target>".


Here's the makefile as it stands:


piece = stamitz
LILY_CMD = lilypond -ddelete-intermediate-files \
                    -dno-point-and-click

.SUFFIXES: .ly .ily .pdf .midi

curdir = $(shell pwd)
VPATH = $(curdir)/Scores $(curdir)/PDF $(curdir)/Parts $(curdir)/Notes

%.ly: %.ily
%.pdf %.midi:  %.ly
        cd PDF; $(LILY_CMD) $<

.PHONY: score
score: $(piece).pdf

.PHONY: parts
parts: cello.pdf violinOne.pdf violinTwo.pdf viola.pdf oboes.pdf horn.pdf

.PHONY: movements
movements: $(piece)I.pdf $(piece)II.pdf $(piece)III.pdf $(piece)IV.pdf
