> Here's a start on a cluster-chord function.
I don't have the answers to your function-coding questions,
but I thought I'd share a little more of my work with
generating basic clusters manually. My original idea for a
cluster function was to automate this mess, but I had to
Some issues (number 7 is the real pain):
1. There are more cluster-styles out there. I wish I had
access to the Kurt Stone and Gardner Read books, and at
the moment, there are a lot of composers who've used
keyboard clusters, and I don't own their scores: Crumb,
Stockhausen, Berio(?), Cage(?), and Ligeti (in the organ
2. if the function finds notes INSIDE the chord that are not
either of the 2 outer notes, it should at the very least
suppress the printing of the accidentals. Even an
unaltered note within the chord may be given a courtesy
accidental, which would likely be unwanted.
3. I had intended to have my function remove any given inner
notes, and then add ALL the natural (ie. not sharp or flat)
notes between the the 2 outer notes, so that a new stencil
is drawn for each note. I haven't studied your function to
see if that is what you are doing.
4. clusters with different outer- and inner-note-heads
(like "full-width" "Cowell" and "Sciarrino") are tricky
for half- and whole-notes because the inner-note-head
stencil must not cover the inside of the half/whole-note.
Experience has shown that 2 inner-note-head stencils are
needed in these cases: 1 that I called "OuterLink" that
can sit directly above or below an outer-note-head
(these tend to be shaped like bow-ties); and another I
called "InnerLink" which is usually more like a rectangle.
5. some cluster-styles (like "Sciarrino", for example) align
the cluster on the stem-side, so the function would need
to detect the stem-direction, and adjust the stencil
6. some cluster-styles (like "Cowell", for example) have
stems which only connect to one note. I've solved the
problem manually here, but the problem will ultimately
have to be solved dynamically.
7. the appropriate cluster-width for "full-width" depends
on a lot of different factors. First of all, quarter-
notes, half-notes and whole-notes have their own unique
note-head-width (1.3125, 1.39, 1.98 respectively, at the
default staff-size, according to my own measurements),
and secondly, there are 8 different font-sizes for the
Feta font, and the note-head-widths are not scaled
evenly (this is intentional). I don't know how to
dynamically find the current staff-size. And for what
it's worth, the "font-size" and "staff-space" properties
may also affect width (and height, as well), and I don't
know how to detect these dynamically either. Finally,
all of this may affect other styles (like "Cowell" and
Well, the way I've conceived it, this is a big project. I've
been meaning to tackle it myself, but a little bit at a time.
Seeing your enthusiasm has prodded me to share my unfinished
work, however, and if you're up to it, feel free to take
advantage of the work I've done so far.
I've attached my work to date on the quarter-note styles,
designed for use with the default staff-size (20), font-size
I've done some work on half- and whole-notes, but I'll leave
that for another post.
Hope this helps!
