At present this is only implemented in
jcabc2ps.
It allows the usual K:<tonic><mode> to be followed
by a list of accidentals which are added to the key signature.
Just K:
This is a rest that isn't shown but is played.
It is mostly useful in multi-voice music,
to cut down on the clutter of many rests.
This is a "rest" that takes space on the screen or paper,
but is ignored otherwise. Players should ignore it entirely.
This is not part of the standard yet, but is implemented by a few ABC tools.
In the past, a lot of ABC has mis-used the "text" chord notation to place
arbitrary text above or below the staff. The proposed extension uses:
PostScript is the language accepted by most laser printers,
and can produce very good-looking printed music.
This means that the program plays the music using the computer's sound card.
MIDI is the Musical Instrument Digital Interface,
the most widely-used encoding scheme used by electronic musical instruments.
Global accidentals
Free Meter
Multiple time signatures
x: invisible rest
y: invisible and unplayed rest
Lyrics under the notes (w: lines)
Annotations: Quoted Text
The idea is that the ^ and _ characters tell the software
that this is not the name of a chord, but just plain text. The initial
flag character will be stripped off, and the text displayed above or below
the staff, hopefully in a position that doesn't clash with other symbols.
We expect that eventually the common musical terms may be recognized and
interpreted by player programs.
