The Petrucci Music Font which comes with Finale* has various diamond and
square shapes which can be scaled and used for note heads.  Finale* also
lets you choose any font for use as the primary music font so you can
design and import your own.

I have use dLime for a few weeks now, it is quite versatile.  It uses
the "Marl" and "Tufa" fonts for most of its work.  It can also use the
"Sonata" and "Interlude" fonts, which you must buy from somewhere(??).
But, of course, you can used ResEdit to tweak the Marl and Tufa fonts
to get variants of the note shapes suitable for you Gregorian chanting...

The first stop should probably be Deta S. Davis' bibliography of 
computer applications in music published by A&R Editions [there's
an update to the 1989 volume out now as well], where you'll find an
entire section on just that topic. There should be plenty there [and
sources from *outside* the Computer Music Journal as well - those can
be harder to locate] to keep you busy. A&R Editions has also recently
published David Cope's book on using computers for stylistic analysis.

Your library should have them, or interlibrary loan can find them.

I may speak for our group of the Computer Science Department in 
Karlsruhe (Germany), where we have a project running about 
musical analysis with neural nets upun music in the style of
Bach,Reger and Schuetz.The program is called Harmonet, because
it analyses the structures of the counterpoint of a choral, and
then finds a counterpoint of a new melody in the style of that
particular componist.The output is given in a midi-file so that
we can listen to it on a digital piano. The progam Harmonet is 
indeed quite large and written in Lisp that runs on our Sun Sparc.
Only a few of us understand how to let it run. But there are 
existing papers (in German) that are describing the theory of 
preprocessing the music for the neural net (some small papers
are in English).As the principle is very flexible the style
could be very different, but we are still working on it...

Another project follows a more classical aproach. It handles
the music of Mozart and "composes" variations upon his music.
The approach I call "classical" because the concept bases on
"Grammars".


------------------------

Does any other group work on similar projects ?
That would interest me.What I can give is a probe
of our work in form of MIDI - Files on request.

  well, I'm not a group but I am currently working on an independent study
project to generate 50's style music.  The code is to be written in LISP and
I am currently analyzing a number of songs and trying to find threads of
commonality between them to generalize and implement as AI heuristics.  I 
would like to know what other work has been done on this sort of thing, and
where I can read about it, if at all.  thanks...

Just forwarding this to News as requested.  :)

From: Michael Casey <mkc@media.mit.edu>

You may want to consider David Cope's book "Computers and Musical Style"
which is an anthology of the author's work on this very subject;
analysis/synthesis of musical composition. The book includes (LISP)
source code to significant parts o
f his EMI system (Experiments in Musical Intelligence). For the
non-technical reader there is a brief introduction to LISP programming.
There are numerous examples of programs applied to examples from musical
literature, (Bach, Mozart, Schu
bert, Stravinsky and many others). The program produces an analysis of
the regularities in two or more pieces of the same style and uses these
as "signiatures" to generate a new piece in that style. Cope's
methodology is derived from a mixture of classical AI (or rule based)
models and linguistic grammars (Augmented Transition Network).

The results are interesting and can be remarkable. But I have to add
that there are significant problems with the methods. The system seems
good at capturing very local
phenomena, (such as cadence formulae), but is ill-conditioned for
capturing more global
aspects of musical structure (such as melodic coherence, harmonic
interest, &c). These
problems have been acknowledged by the author but I think they are
unsolvable in the
current working paradigm.

There has been much other work on computer-generated and
computer-mediated composition. If anyone is interested I can post a
comprehensive bibliography. Below is a tiny selection that in no way
represents the scope of the available research:-

Subject: X11 music fonts?
To: Music-Research

I'm interested in writing an X front end for MusicTeX (and a number of
other output formats).  I'd like to know 1) if it's already been done,
2) where I could find any X fonts or bitmaps of music symbols.  I'd also
appreciate any comments, suggestions, things to consider....

Thanks,
