Hi, Mats, Christian, and all others on the devel list!
Long ago when lily 1.1.55 came up, mensural time signature styles
old2/4, old6/8alt, old4/8 were added (by Mats & Christian, the
changelog says), using a three quarter circle opened to the left side
(like the letter "C", but reversed on the x axis). My resources (MGG,
Harvard Dictionary of Music, DTV Musikatlas and others) show for (white)
mensural notation only a single form with such a reverse "C", namely
the "tempus imperfectum cum prolatione minori" typus with brevis as beat;
i.e. the reverse "C" equals the vertically slashed "C" (alla breve).
I guess, your resources refer to some notation that was used earlier,
maybe franconian ars nova or something alike. Could you check this and/or
do have you any bibliographic or WWW references?
at the time when Mats on my request created the additional white
mensural notation timesig symbols I had limited access to litterature on
that subject. In the meantime I've aquired the German edition of Willi
Apel's (author of Harvard Dictionary of Music) book on notation "Die
Notation der Polyphonen Musik", Leipzip 1962. According to this book (p.
157 f) the 'inverted' C is one among a series of alternative
(alternative to a fraction notation (2/1) indications of 'proportio
dupla', also denoted 'diminutio' or 'diminutio simplex' which, in case
of tempus imperfectum ,as you write has 2 semibreve per beat.
Please bear in mind that the symbols offered in Mats's adaptions of the
fonts have no musical implications whatsoever - they're just symbols
which you can use as you want. Personally I used them for the 'original
notation' incipits of my MusiXTeX typeset modern editions of works by
Thomas Ravenscroft. You may find these editions on the successor of the
GMD music archive, the Werner Icking Muisc Archive
(http://icking-music-archive.sunsite.dk/) where you'll also find Mats's
feta fonts along with a type 1 postscript version and macros for
This is the best information I have myself. You might want to ask more
intricate questions to Alain Naigeon (address@hidden), who maintains
an interesing web site on early music, see http://anaigeon.free.fr/.
