Hi Kevin, hi Jamie,

Sciarrino uses a downward-pointing triangle for either lip- or
tongue-pizzicato in some of the flute music (which was the reason I
originally posted the list some time back).

Penderecki scores use an upward-pointing triangle to mean the highest
note possible, frequently in the strings.

Both the Sciarrino upward-pointing triangle and the Penderecki
downward-pointing triangle appear with the stem centered directly in
the middle of the notehead (which differs a bit from Kevin's examples,
above).

And, here too, both bits of notation aren't exactly "commonly used"
... at least not yet ;-)

(Sidenote: stem-centering means that intervals of a second are
problematic. But lip- and tongue-pizzicati, on the one hand, and
highest-notes, on the other hand, make sense only as single "notes",
and not as chords. So the problem of the interval of the second never
arises in practice.)

As it turns out, Max already has a working set of examples for
stem-centered triangles and we're currently working through the
possibility of having two different types of triangle noteheads that
point either outward / inward (or up / down) depending on stem
direction. Results look good so far ...
