I recently came across this teaching website:
https://www.mymusictheory.com/learn-mus ... ming-notes
which claims that in 3/4:
"The quavers can be beamed right across two or three whole crotchet beats, but the first note of the group must fall on the beat, not on an off beat."
Ted Ross says: "a beam combines similar notes on adjacent beats", and goes on to say "Notes on the first beat can be beamed with the next", and so on.
Finale splits the beams at the beat in 3/4 -- unless you define it as "1 dotted minim", in which case it also beams 12 semiquavers together...

Dorico beams all the quavers together; though there are a plethora of options for note beaming.
Anyway, I'm working on a piece which has this figure, repeatedly:
Perhaps I've stared at it too long, but I'm wondering if it would be better beamed to the beat? In my head I'm over-emphasising the words "on the beat" in the quotes above.
There are also sections in 6/4, with a similar figure, where I'm more inclined to leave them as one group per half-bar.
Thoughts?
