I don't think people, like me or John Chamber, who want in this
case a more tolerant standard wish to confuse pple with the
notions of slurs and ties. For example B and G *can't*
(physically, in acoustic) be tied, can they ? So we could say this
is just a convention to notate slur *both* with - and (). That
doesn't mean slurs becomes ties. 
And a last remark : in french we only use one word for the two :
it is called "liaison", we would not confuse the two. But I've
just read in a musical theory that there was a difference of
interpretation for slurs according as the slur concerns only two
notes, or several notes : it is said for two slured notes which
are at a different length, the 1st one should be emphasized, i.e.
: (c2B) z/ d/ (d2c) z/e/ | (e2d) /.../
so it's not so illogical to use - to write a slur/tie ("liaison")
between 2 notes (whatever they are and whatever that particular
slur/tie means) and brackets for slur between several notes (more
than 2 at least). For ties between more than 2 notes like
A3-A2-|A2 I don't find it really logical to allow (A3 A2 |A2), but
why not ?

In fact, we can't confuse people; they  are  already  confused.   The
simple  fact is that conventional printed music notation doesn't make
a real distinction.  True, some publishers claim to draw  those  arcs
slightly  differently.  But different publishers use different rules.
And simple examination of a stack of  published  music  will  quickly
convince  you  that  most of them have such poor quality control that
any claimed differences are wiped out in the printing  process.

All you can really say with accuracy is that printed music uses  arcs
that  connect  groups  of  two  or  more  notes,  and these arcs mean
different things in different circumstances.  Any differences in  how
they  are  drawn  are  mostly  accidental  artifacts  of the printing
process, and are best ignored unless you  *know*  that  a  particular
edition is using those differences consistently.

| And a last remark : in french we only use one word for the two :

It's even worse than that, of course.  Those arcs  are  used  for  at
least  three  things in conventional music.  In English, we call them
ties, slurs and phrases.  I haven't yet  read  any  complaints  about
people  using  () in abc to indicate such things as bowing/breathing,
but I suppose I will eventually.  Printed music notates this  exactly
the  same way as it does phrasing.  The only difference is the length
of the group of notes, so it always  requires  musical  judgement  to
distinguish slurs from phrases.

I've seen this, but it's rare.  I think most printers and  publishers
have at least managed to get this one right.  ;-)

In any case, if we want musicians to get such things right in abc, we
really  should  have distinct ways of representing ALL of the uses of
arcs  in  printed  music.   Conflating  slurs  with  phrases,   while
distinguishing ties, is guaranteed to just add to user confusion.

Is there a fourth use of these arcs that I haven't listed?


(Hey. Laura; does LilyPond distinguish all these?  Just curious.)

Yes:

Tie:
  a ~ a

slur:
 a () a

phrasing slur:

a \(\) a

The documentation says:

   Typographically, the phrasing slur behaves almost exactly like
   a normal slur. The grob associated with it is PhrasingSlur , in
   Voice context.  

So the main difference between a slur and a phrasing slur is that
there is a different "grob", so that you can make all phrasing slurs
dotted or invisible while leaving regular slurs alone, or vice versa.

And:

A tie connects two adjacent note heads of the same pitch. When
used with chords, it connects all the note heads whose pitches
match. Ties are indicated using the tilde symbol `~'. If you
try to tie together chords which have no common pitches then
no ties will be created.

With all respect, it serves no one to contribute to this confusion by 
treating things the same that are in all respects different, that is, 
different in the 'language of music'.

More snipping...

This is indeed the real world, and the central issue of my original comments.

Still more sniping...

Now this sounds like a plan... (I hope). :-)

You guys take care and keep up the very good work,
