Hi everyone,

I can't help but to comment on this.

For one thing, how would such an analysis as Han-Wen proposes proceed --
statistically?

>From all of my observation of European hand engraving, clefs only take up
extra horizontal spacing when it is necessary for the sake of fitting the
clef.  Otherwise, the clef occupies as little space as possible - in either
polyphonic or monophonic music.  I could find reams and reams of such
examples.  I would like to see examples of clefs taking up extra space where
such extra space is not "needed" - where it is simply used aesthetically.
The only examples I can find use extra space extremely judiciously - and not
that noticeably at that.

My understanding of the idea is this (not from technical engraving practice,
simply from much observation): horizontal space is primarily concerned with
rhythmic representation.  Time signatures obviously take space because they
occur at the beginnings of measures, as do key signatures (usually).  A clef
takes up unnecessary horizontal space within a measure when the note-to-note
distance occupies more space than is needed for the notated rhythm *and* the
clef would comfortably fit in less space.  Clefs taking up this kind of
space skew the rhythmic representation in horizontal space.  As a performer,
I find this unnecessary clef space distracting - the rhythmic "skew" throws
me off.  And as an observer of hand-engraved scores, I can't seem to find
substantial examples of it.

It seems to me clefs should be horizontally "invisible" unless they can't
fit otherwise.

Hope that helps.  I'll keep my eyes peeled in a sort of informal analysis.

I could follow this up with a discussion of the merits of Joe's
space-to-barline property, which I think has promise...

And many, many thanks for the efforts to improve this excellent program.

Neil
