OK, let's see if I understand this. (It's always easier to ask a
question than to read text carefully): a specification or a change in
meter/key/whatever will apply to all voices, *unless explicitly changed*
by an (inline?) specification. But the inline specification applies *only*
to the one voice.  So there is a fundamental difference between inline
changes (presumably enclosed in square brackets) and (what do you call
non-inline changes? Outline?) those specified by a field starting on a
newline (which can not be enclosed in square brackets, or else the email
linebreak demon will foil the best intentions), in that the inline changes
are local, the outline (sorry! I'd better use quotes on that!) are global.  

So, the order of voices in the abc is usually not important,
*except* in the case of an "outline" change, which will presumably apply
to all subsequent voices, as written in the abc.  Or am I confusing
things?

I couldn't find that---got the earlier version, but not
the second.

May be interesting to note that my program HARMONY provides tablature for
Anglo Concertina (and Melodeon). I don't know of any other abc program which
does.

Nice work Guido! After doing a pdf2gif conversion of the English version 
I have updated the

I appreciate precisely what you are saying, but it seems to me we are 
complicating matters. Meter changes will generally be global and in 
that case we can write the input for all voices for the first part of 
the tune which is in the initial meter.
Follow this by an M: field
Then continue with the input for all voices for the section in the 
new meter. If we need to change the meter for one voice then this can 
be done with an inline field

I suggest an exactly similar argument for Key changes.

I include a section from my suggested modifications to the ABC-
standard at http://www.nspipes.co.uk/barry/abc2propos2.html


-

Multivoice notation includes all situations where multiple input 
lines are to be aligned in the output. The simplest cases are perhaps 
one voice and aligned words or symbols or chords. The fields which 
can be involved are: V: (voice); w: (aligned words); s: 
(symbol lines); and c: (chords).
 
 

K:specification %start of tune.

  %these should be unnecessary at his point.
Multivoice block

Multivoice block
.
.
Multivoice block
Blank line

The Multivoice block consists of the fields mentioned above. and 
might look like.

V:1 cAB2 |cAAA |c3B|G2+fermata+Gz ::e4|\
w: que-sto~il vi-so ond' io
ri-man-go~uc-ci-so. Deh,
w: ran-do fi-so, tut-to re-stai
con-qui-so.
V:2 AAG2 |AFFF |A3F|=E2+fermata+Ez::c4|
V:3 (ag/f/e2)|A_ddd|A3B|c2+fermata+cz ::A4|


A section of one voice is notated . The equivalent section of all 
other voices are then appended along with symbol lines, guitar chords 
and inline words. All voices can be multiline. The voice, chord and 
symbol lines do not have an included space when joined.  Inline 
fields e.g.[M:4/4], [K:G] apply only to the voice in which they 
occur, but fields between blocks have a global effect across all the 
voices.

The first voice in the block controls line-continuation and line-
breaking for the whole score so the \ at the end of the V:1 field 
merely indicates that this is not a staff break.

You need to place a metre change in all of the voices (if that's what you
want) since you can have voices in different metres.  (It's not common,
but it does happen, and not only in avant-garde music - Bach did it
occasionally.)

Yes, that's perfectly acceptable, but you still need to put fields
in all of the voices to which they apply.  There's nowhere in the
tune body where you can place a single field and have it apply to
all voices.

My major objection to inline fields is encapsulated in the statement 
from ABC2.0 rev IV


---

To avoid ambiguity, inline fields that specify music properties 
should be repeated in each voice. For example,

...
P:C
[V:1] C4|[M:3/4]CEG|Gce|
[V:2] E4|[M:3/4]G3 |E3 |
P:D
...

-

the need to align the meter change in every voice seems a great 
problem in parsing. What action does the program take when one voice 
out of eight does not align.

ABC 2.0 states


For backward compatibility, it is still allowed to notate tune fields 
on a line by themselves, between the music lines:

ed|cecA B2ed|cAcA E2ed|cecA B2ed|c2A2 A2:|
M:2/2
K:G
AB|cdec BcdB|ABAF GFE2|cdec BcdB|c2A2 A2:|



If we are considering multivoice notation, this seems a far more 
sensible way to notate global key and meter changes than having to 
match inline fields in all voices.
