If you're just wanting to put a few symbols in, you may find Anastasia (TrueType) already on your machine.

On newer machines, one or two of your fonts may be "full" Unicode, and able to print a few strange characters. "Arial Unicode" may be on your install disks, although it doesn't normally install in a default setup - because it's rather large. You can enter the "code" on the Number Pad while holding the Alt key, and you may get something. The problem is in identifying the correct code for the few characters you want.

If you've used any notation program, there's a good chance that you have some, or all of the TrueType fonts:
Frets A
Frets B
Frets C
Maestro
Maestro Percussion (Maestro also available as Type 1)
Opus
Opus Chords
Opus Percussion
Opus Special
Opus Text

Be aware that with any of these "music fonts" character size and spacing can be "strange."

Separated individual characters are not too commonly used in text. If you're actually wanting "scraps" of notation, you can zoom in as much as possible in any notation program, Alt-PrtScrn, to capture a picture of what's on the screen, Ctl V to paste it into Word and then crop down to leave just what you want. With some programs, there are better ways of doing it, but the "screen shot" works fairly well with almost any program.
