If the character is contained in the font, you could use the Glyphs panel to type it if you don't know the keycode. Otherwise you'd first have to edit the font with a font-editor or use a font that already has it.
If you're on Windows you can use the font musical.ttf if it is installed on your machine. If not, search for that font
"musical.ttf" on the internet and purchase and download that font, or just download it if it
is a freeware font. The friendly font name is called "Musical Symbols"
You might want to purchase an OpenType font (for its cross-platform capabilities). If so, you can purchase Sonata from Adobe Type ($29) here:
You'll still have to use the Glyphs panel to access the characters.
Thanks, guys. I went with the musical.ttf option. I'm surprised the Times New Roman font doesn't have its own music symbols (even in the glyphs) in Illustrator, considering the exact same font has them in MS Word.
considering the exact same font has them in MS Word.
It probably doesn’t. Word is probably accessing another font for certain symbols. If you doubt me, make PDF of the Word file with that glyph and open it in Acrobat, then look at Document Info/Fonts panel.
