I want to be able to generate graphic musical examples without getting

accomplish this?
I cannot find anything in the manual which allows this.
I assume you basically want to trim your output to the really used space.
I guess there should be an option to do so, since it's done for the
snippets in the documentation, and it might well be the clip-systems
option. However, this one does exactly nothing for me (2.12.1), or I
just can't use it correctly.
If you have ImageMagick ready, for PNGs you can just call
convert -trim original.png trimmed.png
If you want trimmed PDF and/or EPS files and are on one of the common
Unices with ImageMagick/GraphicsMagick, GhostScript and xpdf-utils
installed, have a look at the attached Makefile.
Note that I don't simply use the above command for the PNGs, but convert
the PDF to PNG instead; this way, the sizes of both images are exactly
the same (up to the resolution).
If you remove the -l option from the ps2eps call in line 16, the PDF
should be trimmed "tight"; with it, there is a white border of about 1pt
around it.
I have no idea what this does to multipage files, by the way.
HTH,
