Gregorian square neumes notation (following the style of the Editio Vaticana) is under heavy development, but not yet really usable for production purposes. Core ligatures can already be typeset, but essential issues for serious typesetting are still under development, such as (among others) horizontal alignment of multiple ligatures, lyrics alignment and proper accidentals handling. Still, this section gives a sneak preview of what Gregorian chant may look like once it will work.
The following table contains the extended neumes table of the 2nd volume of the Antiphonale Romanum (Liber Hymnarius), published 1983 by the monks of Solesmes.

Unlike most other neumes notation systems, the input language for
neumes does not necessarily reflect directly the typographical
appearance, but is designed to solely focuse on musical meaning. For
example, \[ a \pes b \flexa g \]
produces a Torculus consisting
of three Punctum heads, while \[ a \flexa g \pes b \]
produces
a Porrectus with a curved flexa shape and only a single Punctum head.
There is no command to explicitly typeset the curved flexa shape; the
decision of when to typeset a curved flexa shape is purely taken from
the musical input. The idea of this approach is to separate the
musical aspects of the input from the notation style of the output.
This way, the same input can be reused to typeset the same music in a
different style of Gregorian chant notation.
The following table shows the code fragments that produce the
ligatures in the above neumes table. The letter in the first column
in each line of the below table indicates to which ligature in the
above table it refers. The second column gives the name of the
ligature. The third column shows the code fragment that produces this
ligature, using g
, a
and b
as example pitches.

The following head prefixes are supported
\virga
,
\stropha
,
\inclinatum
,
\auctum
,
\descendens
,
\ascendens
,
\oriscus
,
\quilisma
,
\deminutum
.
Head prefixes can be accumulated, though restrictions apply. For
example, either \descendens
or \ascendens
can be applied
to a head, but not both to the same head.
Two adjacent heads can be tied together with the \pes
and
\flexa
infix commands for a rising and falling line of melody,
respectively.
