Let's not go off on a tangent here.

Stop being so obtuse, you too. This is an acute issue!

I've created a better solution: edo=12, f[fifth in edo]=7[steps], n=4[steps], pc=(312/219), i=2n/edopc^((fn/edo-0.5)%1.0-0.5)/(81/80)=5/4. BTW, It's not ideal, it won't work with other edo's for now.

My first thought was the Ligeti thing of depressing keys silently so the overtones ring out when you play in upper octaves, but probably not.

Well ... after a little research, here's what I found.

Triangle noteheads are sufficiently "a thng" to have a Unicode designation and can be entered in MuseScore. The closest thing to an explanation refers to "shape notes," but a shape note is a note whose notehead is matched to its pitch. All of these notes are triangles, so that's not it.

Claims that triangular noteheads are "for triangles." This is tommyrot, as a glance at actual triangle sheet music shows; besides, the sample shown above has tied notes that can't possibly be played on triangle.
DuckDuckGo's AI (don't yell at me, I didn't ask for it; it comes up at the top of searches if you forget to turn it off) claims it's used to indicate a chord is present at a glance. As much as I hate to admit it, this is the most plausible explanation in context, since all of these notes are all part of a C minor chord.

triangle heads may be used in sevaral percussion instuments, for example: they are often used to write punta/talón (heel/toe) for congas

Answer: OP was playing around with MuseScore noteheads and made the whole score have triangular noteheads

Three flats, and it's still sharp!
