If you are using Ghostscript, there are two utility programs included with
Mup for displaying and printing music.
mupdisp Mup_options myfile
mupprnt Mup_options myfile
The Mup_options can be any of the options listed in the section on "Command line arguments" except -f, -m, -M, -r, or -v, which don't send PostScript output to the standard output.
The Mupdisp program allows you to view pages in any order, with either a version small enough to fit on your screen or a near-actual-size version that you can scroll if it doesn't fit on your screen. Mupdisp will run under MS-DOS or will run under UNIX with TERM of AT386, linux, or xterm (under X windows).
Mupdisp begins in partial page mode, which displays output at approximately actual size (depending on the size of your monitor). In this mode, most likely not all of the page fits on the screen, so the scrolling commands can be used to move up and down to view different parts of the page. In full page mode, a small version of the entire page is displayed. This is useful for seeing overall page layout, but is generally too small to see much detail.
Once the music has been drawn on the screen, you can enter various commands to view different pages or parts of the current page. The commands are:
When in X windows, the mouse can be used for scrolling. The left button scrolls downward like the f command, while the right button scrolls backwards like the b command.
