 Patrick Andries enquired:

  2) U+1D1C0 seems to have an incorrect names (e.g. "fusa black"). This is
  character (SEMIBREVIS BLACK + STEM +  FLAG-2)

  I believe, this is black SEMI-FUSA. [snip]
  I believe the confusion may stem from the fact that some symbols have
  change names and values through time (see below). Unicode seems to have
  aligned itself on the pre-1420 names (the smaller set of symbols) and
 have
  extrapolated from it the names of the black notes that appeared only
 after 1420.

 No, I think the Unicode terminology is correct. The name "fusa black" has
 not been extrapolated anachronistically. It was indeed used like this
 pre-1420 (although the dictionary table you quote doesn't show it.)

OK. If this "fusa black" is indeed attested, I stand corrected.

May I add  that I believe this is not the most common name : I did check
this in three different small music dictionaries (and many Web pages) and
they all show that this note appeared late (post-1420) and give it its
post-1420 name : "semi-fusa". Could it be that Unicode has adopted a rare
name for this character and that this could confuse modern users (they are
quite a few pages on the Web concercing this topic) ?

 The
 Unicode terminology is consistent in so far as all white notes are given
 post-1420 names, and all black notes are given pre-1420 names,
 notwithstanding the fact that these black notes were also used with
 *different* names and values post-1420.

Which I believe is confusing (see your table below).
All notes could have been given post-1420 names given the fact that the
white notes appear only after 1420...

 semibr. = white head(=1d1b9 "semibrevis white")*
 minima  = white head + stem (=1d1bb "minima white")**
 semimin.= white head + stem + flag1 (=1d1bd "semiminima white"), or:
   black head + stem (=1d1bc "minima black")***
 fusa= white head + stem + flag2 (=1d1bf "fusa white"), or:
   black head + stem + flag1 (=1d1be "semiminima black")
 semifusa= black head + stem + flag2 (=1d1c0 "fusa black")*

Found this original illustration
http://www.music.indiana.edu/tml/16th/FABCOM_04GF.gif
in Compendiolum musicae pro incipientibus, 1594.

 You can see that the Unicode terminology is consistent with all of the
 pre-1420 symbols, and at least with one of the two sets of post-1420
 symbols. (Even if that is not the set of symbols that eventually came to
 dominate.)

Exactly.

Thank you, Lukas.

P.S. Incidentally, do your sources also show consistently the nominal form
of the MAXIMA and LONGA with stems pointing downwards contrarily to the
Unicode reference glyph ?

 white notes appear only after 1420...

Well, not really, because there are quite a few symbols (black notes of
semibreve and above) which occur only in the pre-1420 notation. So the
series of "black" note names would have a confusing gap:

"black head with no stem" = "black semibrevis"
   = no "black minima" 
"black head with stem"  = "black semiminima" (new usage)
"black head with stem and flag1" = "black fusa" (new usage)
"black head with stem and flag2" = "black semifusa" (new usage)

"white head with no stem" = "white semibrevis"
"white head with stem" = "white minima"
"white head with stem and flag1" = "white semiminima"
"white head with stem and flag2" = "white fusa"
etc.

That's what your proposal boils down to, isn't it? Well, certainly
historically correct, but I find it even slightly more confusing than the
other way. I do think that the terminology Unicode has chosen is the more
consistent one. Confusing, yes, but it *will* be confusing to
non-specialist users either way, won't it?

Oops, indeed, they do, and I hadn't noticed. (As I said, my musicology days
at university are way back...) -- This might very well be significant. Yes,
I think mensural notation did not have the modern convention that the
orientation of the noteheads depends on the position on the stave. Hold on,
I'll check.

I also notice that the "black maxima" seems to be missing. Since we have
the "black" and "white" series, we ought to have them both complete, right?
"black longa" can be thougt of as unified with Gregorian 1d1d3 "virga", and
"black brevis" with generic 1d147 "square notehead black", but the "black
maxima" isn't there.

Maybe not. As I mentioned in my first message, I believe these are font
variants (they
have the same names and values). If you have a pre-1420 font they are
whites, after they are black (they do
not usually appear simultaneously) . I may be wrong on this, please feel
free to correct me.

 That's what your proposal boils down to, isn't it?

No, IMHO, the black pre-1420 variants should not be coded and named.

I see, siding with authority...

 non-specialist users either way, won't it?

I don't think so, this is the practice adopted in most (short) musical
dictionary, like the one you quoted :


Post-1420 (when black vs white noteheads became distinctive:)

semibr. = white head(=1d1b9 "semibrevis white")*
minima  = white head + stem (=1d1bb "minima white")**
semimin.= white head + stem + flag1 (=1d1bd "semiminima white"), or:
  black head + stem (=1d1bc "minima black")***
fusa= white head + stem + flag2 (=1d1bf "fusa white"), or:
  black head + stem + flag1 (=1d1be "semiminima black")
semifusa= black head + stem + flag2 (=1d1c0 "fusa black")*


I  would suggest (and I was wondering about using it for ISO 10646 1st Amdt
of Part 1 French translation) to use the first column names with their
post-1420 form, all lay books seem to use them. My problems are the
superfluous (pre-1420) black forms (the historical glyph variants) which
would still have to be named. Note that I fully accept that I may err and,
in fact, do not want to push my point too hard here, not being a specialist.

Yes,
 I think mensural notation did not have the modern convention that the
 orientation of the noteheads depends on the position on the stave.

As far as the stave position is concerned, it may well well vary; but are
the reference glyph stems in musical books not predominantly down for those
two notes? (see http://www.music.indiana.edu/tml/16th/FABCOM_04GF.gif,
1594).

  Hold on, I'll check.

Not missing, if the black variety is simply an historical glyph variant.

Patrick Andries has answered this point, suggesting that
the black and white variants should be seen as font variants.
I guess that's a valid point, but it raises the question why the other
musical notes aren't unified in the same way. There are separate characters
(1d1b9) "SEMIBREVIS WHITE" and (1d1ba)  "SEMIBREVIS BLACK". Note that these
symbols are *not* affected by the semantic ambiguity problem we were
discussing, which involves only the smaller note values minima, semiminima,
fusa and semifusa.
I'd be interested to learn the rationale behind these choices. Is the
original proposal available anywhere?

As for the other question, that of the stem of "longa" and "maxima": Yes,
Patrick's suggestion is right that the most common form of these notes has
a downwards stem (on the *right* side of the notehead, mind!) In earlier
mensural notation, the directions of noteheads did not depend on the
position of the notehead on the stave, as today; rather, minims and other
small notes always had upwards stems and single longae and maximae mostly
had downward stems. However, the odd example of longae with upward stems
can be found even then. From the mid-16th century onwards the modern
convention of context-dependend stems seems to have emerged, and from then
on both the longae and the minim stems were placed according to it. So, it
seems consistent that the Unicode charts show all notes with upward stems,
implying that upward and downward stems are context-dependend glyph
variants.

Plenty of examples of all this can be found in: Willi Apel, Die Notation
der polyphonen Musik 900-1600. Leipzig 1962/1970.

Try:
http://viva.lib.virginia.edu/dmmc/Music/UnicodeMusic/

That's Perry Roland's original proposal, with a lot of examples.  I'm not  
sure you'll get much rationale, however, for the names.

Regarding yesterday's question by Patrik A.:

 1) Where is the Gregorian punctum (square dot) ? Is it unified with another
 dot, another shaped note (U+1D147) ? If so, why ?

First, I believe what Patrik called "punctum", meaning the Gregorian  
"brevis" (terminology according to Apel's Harvard Dict article "Notation".)  
 The (Gregorian) "brevis" (square) is unified with the square notehead  
U+1D147; and the (Gregorian) "semi-brevis" (diamond or lozenge shape) is  
unified with the U+1D1BA.  Thus, Gregorian notation, medieval notation, and  
modern notation require either separate fonts in practice, or need "font  
features" to   differentiate subtly different shapes if required.

Please note that the SCOPE of the current set of musical symbols is mainly  
sufficient for general use in plain-text discussions and so forth.  At  
some point, there will probably be another proposal for more characters.

In particular, there might be a need for further neumes and more obscure  
symbols.  However, gregorian notation is expected to make heavy use of  
ligatures, not all of which should be encoded.  The quilisma in particular  
I think needs to be added in a subsequent proposal.

Re: Square and lozenge notes -- Musical Notation 3.1 --Mensuralnotation

2001-03-07 Thread Rick McGowan

 Why are the punctum and semi-brevis unified with U+1D147 and U+1D1BA
 since, unless I err, they do not share the same value but only a
 visual similarity

Well... the rationale for that would be the same thing that unifies the  
"." in "3.14" and "Mr. Fung".

However, in this case, it's true, that they might be better dis-unified  
and we are considering that.  The PUNCTUM (brevis) most often has a  
slightly convex upper side and concave lower side while the square notehead  
of modern music is really square.

P. Andries asked:

 dot, another shaped note (U+1D147) ? If so, why ?

I am double-checking, but I believe it's unified.  I'll have more info later.

 2) How would a triplet (a group of three notes to be performed in the time 
 of two ordinary notes of the same kind) be represented ? By the addition of 
 a subscript/superscript number 3 (which one ?) to a series of beamed notes ? 

That is entirely up to the layout program.  I would suppose use of a small  
italic "3", with or without accompanying brackets, depending on the  
typesetter's preference.  This aspect of layout is beyond what Unicode is  
providing.

Square and lozenge notes -- Musical Notation 3.1 -- Mensural notation

2001-03-06 Thread Patrick Andries



I have a few questions about the Renaissance 
musical symbols found inits proposed 3.1 block.

1) I do not see why the notes U+1D1B6-U+1D1C0 are 
divided in three different groups, one of them grouping miscellaneous 
symbols.


2) U+1D1C0 seems to havean incorrect names 
(e.g. "fusa black"). This ischaracter (SEMIBREVIS BLACK + STEM + 
FLAG-2) 

I believe, thisis black 
SEMI-FUSA.Itwill eventually producethe 16th note (in Unicode's 
American imperialist terminology) or the semi-quaver (in the tongue of the 
Great-British); the lozenge headnote having been replaced by an oval 
one.

I believe the confusion may stem from the fact that 
some symbols have change names and values through time (see below). Unicode 
seems to have aligned itself on the pre-1420 names (the smaller set of symbols) 
and have extrapolated from it the names of the black notes that appeared only 
after 1420.


Name 
Pre-1420   After 
1420 
SEMIMINIMA U+1D1BE 
   U+1D1BD or 
U+1D1BC
FUSA  
  ---  
  U+1D1BE
SEMI-FUSA--- 
   U+1D1C0.

May I ask why the larger set (post-1420) was not 
used ? This would not have lead to any errors in naming but present only a 
*glyph* ambiguity as far as the SEMIMINIMA/MINIMA/FUSAare concerned. In 
other words, should this be displayed with a pre-1420 font ?

Quick tangential correction to that table that Patrick Andries supplied a
link to: it seems to imply that the Greek accents were musical notation;
they were not.  For ancient Greek musical notation see M.L. West, *Ancient
Greek Music*, pp. 254-276, especially the table on p. 256.
