Historical lute tablature notation had a number of issues to deal with when it came to indication of rhythm. Remember that this was the late renaissance, at a time when the notation was being simplified (see Thomas Morley, _A Plain and Easy Introductiuon to Practical Music_.
A Composer then had a choice of what note to assign his tactus to. If the musical form was in any way trinary (eg, a galliard, or a bransle simple) it was considered apropriate to use the longer durations which could be 'perfect' (maxima, longa, breve, semi-breve) one unto another. But if binaria sufficed, the lesser notes could be taken advantage of, semi-breve..semifusa; and these had the advantage (to us) of all being stemed. Thus, the solution lies in 'reduction'; ie, advise users against the use of half notes and longer in new composition; transliterations should employ reduction (eg, half->quarter; quarter->eighth ...). The odd breve is found in some renaissance lute tablature, it has a stem toped by a left-going flag or has a circle (at half-mast). \ \ | / |. \ o | | | | | ___________________ ___________________ .. -- Dana Emery _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
