Time Sig: 3/4
Seems like the Factory default should work in 3/4.
Go to notation options>beams and check the very first option there.
[3]/4 works but might have unwanted consequences.

Since it’s a very common notation, I agree that it would deserve a Notation Option. I think it has already been discussed here.
I understand it is discouraged, because it is confused with 6/8.
Yes. Western notation rules taught in basic theory and composition classes would have the first 8th/quaver not beamed to the last two. Adjusting the time signature as previously described by @John_Lilja would probably be the correct way to have all three beam together.
That’s not to say that modern music cannot break the rules but just that Dorico probably will not help with that minor form of anarchy (not judging). The only other option is to manually beam them together by selecting all, right clicking with the mouse, Beaming->Beam Together.
Modern music and Schubert!

Schubert - what a rascal!
I still wanted to quickly double‑check that I wasn’t saying something incorrect, but everything I’ve seen confirms that beaming the last three eighths together in a 3/4 is really frequent, not to say the norm, at least from Bach until the early XXth century.
Some examples
Bach (Bärenreiter)
Beethoven (Henle)
Brahms (Henle)
Brahms (Peters)
Brahms (Simrock)
Chopin (Paderewski)
Debussy (Durand)
Mahler (UE)
Mozart (Bärenreiter)
Manuscript of the same:
Prokofiev (Boosey & Hawkes)
Ravel (Durand)
Schubert (Bärenreiter)
Schumann (Peters)
Schönberg (UE)
Johann Strauss (Breitkopf)
Stravinsky (Dover)
So, yes (while I understand the objections), I vote for a Notation Option
(btw this is already the way 6/4 is displayed by default)
I can’t agree more.
I think it is absolutely fascinating that various publishing houses contradict what we were taught back in the late 70s and early 80s. To me, it simply means that there are more ways than one to “correctly” notate many patterns and, in particular, the one in question here. Great examples!
This beaming is so frequent and so musically logical that it absolutely needs an option. I’m a little surprised at how often notational conventions such as these are dismissed with some theoretical argument that does not take any account of centuries of music writing and engraving.
Depending on your notation options settings, an eighth rest followed by 3 eighth notes can automatically beam together. If you have four eighths where the first needs to be flagged and the last three under one beam, select the 3 to be beamed, hit “j” for the jump bar and type “beam together”. You might be able to set a key command (or macro) for that.
Unless I’m mistaken, the figure which this thread talks about (the isolated last 3 eighths of a 3/4 bar beamed together) cannot be automatically produced in Dorico.
I can’t edit my post anymore to add examples, but I’ve come across plenty more since then — like Tchaïkovsky 5:
I do think the wording of that beaming option is misleading/wrong.
“Beam together a[n eighth] group of any size” really ought to do just that!
Yes! The frustrating thing being, it does exactly that, apart from the last three 8th notes in the bar.
I’m sure you are correct…. I quickly jumped into Dorico on my iPad and mistakenly used a 4/4 bar. I had forgotten it was to be in a 3/4 meter. Still, the “beam together” works, no? I realize it’s not automatic but can it be somewhat automated?
(BTW — My much earlier reference to Schubert was that this figure appears frequently in the 1st movement of his 8th symphony — which looks like the original post!) I think this really needs to be an option!
Well spotted, @jaskarbong! Yet another great example:
Since “Beam together” is not a property, I think there is no way to select all the figures and to change them all at once. So, either one by one (quite tedious even with a shortcut), or hidden local 6/8 or [3]/4 for some sections, or copy/paste and lock duration…
I like the hidden 6/8 idea — sounds like a plan! (I had actually started to transcribe the Schubert #8 when I first got Dorico and Note Performer to get an idea of what it could do. When I saw the post, it looked very familiar!)
