In Emacs, move the cursor to the interesting character, then press

  C-u C-x =

to see the current character's information.  For example, I get the
font

  -Free-Musica-normal-normal-normal-*-18-*-*-*-*-0-iso10646-1

for character U+1D132 (since I haven't a special font setup for Emacs,
it takes a loong time on my GNU/Linux box until this glyph gets
displayed – this is probably a bug in the Emacs version I use).

If I now say

  fc-list -v | less

I can search for `Musica', and I get font
`/usr/share/fonts/truetype/Musica.ttf' as the result.

Another solution to search for fonts that contain musical glyphs in
the U+1D1xx range is to say

  fc-list -v | grep -50 01d1: | less

If you see many `f's in the `01d1:' line chances are high that musical
glyphs are covered.  Such fonts could then be set up in Emacs for
covering the Unicode block.  On my box I additionally get `Symbola',
`Noto Sans Symbols', and `Ostrich Sans Bold' (the last one is a fake,
containing empty glyphs instead).
