Well, why would the sans-serif font be TakaoPGothic in the first place?
I think we should be using the same default fonts on every installation.

We don't use any particular font for sans-serif and monospace. LilyPond 
simply calls the OS's default here.
Which is something I'd like to raise (once more?): Would it be an option 
to find suitable complementing fonts here, ship them with LilyPond and 
make them the default? I think chances that a default sans-serif is 
anywhere near visually suitable for a LilyPond score are pretty small. 
Usually they are chosen for very different purposes (i.e. clean screen 
display for user interfaces). While I think DejaVu Sans (default here) 
is a good font for its purposes it's really ugly when used in a LilyPond 
score.

As first measure we should just use one of the 11 or so standard
PostScript fonts.  Probably Helvetica and Courier for sans serif and
monospace, respectively.

Mhmm.  If we are going to ship a sans-serif font, I strongly recommend
something prettier than those two butt-ugly fonts.

They are required fonts.  Now shipping and installing fonts of our own
additionally would not make a fundamental difference since we are
shipping and installing our own music fonts anyway.  But fonts with a
reasonably complete coverage of Unicode do not exactly tend to fall from
the trees and take a lot of space.

I don't think Helvetica is visually much better, but I agree that it

It is not a matter of "better" but of reproducible scores.


As it is now compiling scores using sans-serif or monospace (without
explicit font selection) can come out quite differently on different
users' computers.


Which is bad.

That is an interesting case. It would seem to me that ideally there

Do I get this right: Setting Helvetica and Courier as default would not

If this is the case I would ask for the following:

1) Set these fonts as default.
This is not sufficient from the perspective of LilyPond's aesthetics but 
it would stop the inacceptable state of scores compiling differently on 
different systems. This should be a straightforward, small patch that 
should be done independently from 2) (I just don't know where to start 
with that).


2) Find suitable fonts and include them in the distribution
I know this is a more difficult issue than 1) but I think it would be 
worth it. By default LilyPond scores don't use sans or monospace (IISC) 
but I think LilyPond should actually provide beautiful defaults for 
these too.
Maybe it would be a good start looking for fonts in the same sources as 
CenturySchoolbook?

Very much so.  And if that happened because Pango picks a default system
font, I would not really be surprised.  Different stuff is suitable for
menu fonts and for music printing.

This is another reason for having a sans-serif font included into the
lilypond distribution, IMHO.

TakaoPGothic is Japanese sans-serif font.
It is only one sans-serif font in the system.
The system doesn't have any other sans-serif fonts.

I'll try to install DejaVuSans and check again.

GhostScript should _always_ have Helvetica in some form available.
I don't think we should give Pango the freedom to pick platform fonts
that are not explicitly selected: that is something that may make sense
for some application with a focus on interactive music display.

But LilyPond targets primarily print.

I've checked.

The result is ligatured.
Lilypond select DejaVuSans as sans-serif font.

As of 2014, Google has released a free unicode sans-serif font, Carlito:

I don't know if it is any better than Helvetica or Arial.


I don't think so.
However, "better" can only be considered in terms of "visually suitable" 
in the context of LilyPond scores.
I think the fonts we're looking for should have a similarly classic or

Maybe we should look for fonts that (optionally) ship with texlive.

I think that the following show some promise:

Alegreya Sans

+1. The entire Alegreya family (also the serif) is beautiful, is not too 
wasteful with horizontal space, and comes with a large set of variants 
(including proper small capitals). I like it a lot in scores.


Another font I used is Optima. It's almost overused, it's not a strict 
sans-serif in my opinion, because the varying widths of the strokes give 
the impression "fake" serifs to some degree, but it's beautiful. And 
with MgOpen Cosmetica, URW Classico (one of GS default fonts) and Linux 
Biolinum, there are a number of high-quality free siblings.


W.r.t. a monospace font, the M+ font collection comes to my mind. It has 
some nice families which look good in print, too. It's a large 
collection, but e.g. M+1m or M+2m should be enough. (Although the latter 
has a pretty unique character with it's g glyph; not sure if that fits 
overall.)



Just my 2 pence,

which recommends Franklin Gothic and Helvetica.  Neither one looks
particularly good to me.


I think so too. But Franklin Gothic was a font I looked at for a longer 
time earlier today ...

Of course the question is always to find a font that is
- free
- good quality
- well equipped with multilingual characters
(- ideally it would also have a number of widths and weights)



There is a large set of Google fonts, many of which are available under
the SIL Open Font License (a free license).  You can see samples at


http://www.google.com/fonts


And filter for sans serif.


OK.  IISC these are web fonts but there are .otf files available in the 
repository.




I think that the following show some promise:

Alegreya Sans
Open Sans
Marmelad
Droid Sans (Apache license)

Some others recommend Oswald from google fonts.

Of course, I'm really bad with making font decisions, but to my eye there
aren't really *any* sans-serif fonts that go well with classical engraving.


Yes, I have this impression too.
I have seen contemporary scores make use of some rather stylized sans 
fonts - but that's something that can already been done, so nothing we 
should consider making the default.


It turned out that I recalled correctly that U.E. made use of sans-serif 
fonts in their titlings sometimes:


http://imslp.org/wiki/Variations_for_Piano,_Op.27_(Webern,_Anton)
http://imslp.org/wiki/4_Lieder,_Op.12_(Webern,_Anton)
http://imslp.org/wiki/Special:ImagefromIndex/313889


In general I wouldn't suggest using sans-serif fonts in score documents 
if it isn't for some special style ideas. But these aren't the target of 
a default font.
But we do have to ensure that the output of a (default) compilation 
doesn't depend on the availability of certain fonts on the user's system 
or on his settings. So we should find a good complement to Century, 
which isn't too easy.
It is so much about the pairing. I have a pair of fonts that I use all 
the time: Minion and Cronos, and I like that very much. But of course 
they are commercial fonts, and they look more modern than the default 
LilyPond appearance. Another quite nice combination (IMHO) is Linux 
Libertine and Linux Biolinum, but that doesn't fit too well with Century 
either.


I think most fonts on Googlefonts are too "modern" by intention. What I 
have in mind would probably be close to the old sans fonts like Franklin 
Gothic or Akzidenz Grotesk.
