### 3.5.4 Replacing the notation font

Gonville is an alternative set of glyphs to Feta – part of the Emmentaler font – and used in LilyPond. They can be downloaded from:

```http://www.chiark.greenend.org.uk/~sgtatham/gonville/
```

Here are a few sample bars of music set in Gonville:

#### Installation Instructions

• Copy the files
```gonville-11.otf
gonville-13.otf
gonville-14.otf
gonville-16.otf
gonville-18.otf
gonville-20.otf
gonville-23.otf
gonville-26.otf
gonville-brace.otf
```

to directory ‘…/share/lilypond/current/fonts/otf’ or ‘…/share/lilypond/X.Y.Z/fonts/otf’.

• If you have ‘gonville-*.svg’ and ‘gonville-*.woff’ files, copy them to directory ‘…/share/lilypond/current/fonts/svg’ or ‘…/share/lilypond/X.Y.Z/fonts/svg’.

Note: ‘gonville-*.otf’ files are for `ps` and `eps` backend (for PDF and PostScript outputs). ‘gonville-*.svg’ files are for `svg` backend without `svg-woff` option. ‘gonville-*.woff’ files are for `svg` backend with `svg-woff` option. For more information, see Advanced command line options for LilyPond.

The following syntax changes the notation font (general and brace) to the Gonville font.

```\paper {
#(define fonts
(set-global-fonts
#:music "gonville"
#:brace "gonville"
))
}
```

Note: Each call to `set-global-fonts` completely resets both the main notation and text fonts. If any category is left unspecified, then the default font will be used for that category. Each call to `set-global-fonts` changes the fonts for each `\book` that follows it, whether created explicitly or implicitly. This means that each `\book` can have its own set of main fonts by calling `set-global-fonts` before it. For more information, see Entire document fonts.

Notation Reference: The Emmentaler font, Entire document fonts.

#### Known issues and warnings

Gonville cannot be used to typeset ‘Ancient Music’ notation and it is likely newer glyphs in later releases of LilyPond may not exist in the Gonville font family. Please refer to the author’s website for more information on these and other specifics, including licensing of Gonville.

#### Other notation fonts

If you have other notation fonts like ‘fontname-*.otf’, ‘fontname-*.svg’, and ‘fontname-*.woff’, you can use them in the same way as Gonville.

That is, copy the ‘fontname-*.otf’ files to ‘…/share/lilypond/current/fonts/otf’ or ‘…/share/lilypond/X.Y.Z/fonts/otf’. If you have ‘fontname-*.svg’ and ‘fontname-*.woff’ files, copy them to ‘…/share/lilypond/current/fonts/svg’ or ‘…/share/lilypond/X.Y.Z/fonts/svg’.

Note: At the moment, LilyPond expects the font file names to have the following suffixes, all of which must be present in the above installation folder(s) to work properly: ‘-11’, ‘-13’, ‘-14’, ‘-16’, ‘-18’, ‘-20’, ‘-23’, ‘-26’, ‘-brace’. For example, ‘emmentaler-11.otf’, ‘emmentaler-20.svg’, and ‘emmentaler-brace.woff’ etc.

The following syntax changes the notation font (general and brace) to the fontname font.

```\paper {
#(define fonts
(set-global-fonts
#:music "fontname" ; font filename without suffix and extension
#:brace "fontname" ; font filename without suffix and extension
))
}
```

Note: For `music` and `brace` categories, specify the font filename without the suffix and extension.
