Usually they indicate whether the grob should be placed above or below
its notehead/notecolumn.  Which is not likely a consideration with
arpeggios.  I'm pretty undecided here.  Using this for arrow direction
may be convenient.  It also seems a bit strange.

Also known as

arpeggioUp = \single \arpeggioArrowUp \arpeggio

if you don't want to look up what the override \arpeggioArrowUp actually
does.

Well the rest of the grob is invariant to rotations so you can't really
tell ;)

While this is true for the current \arpeggioArrowUp and Down commands,
the proposed tweaked arpeggios would need names like
\arpeggioWithArrowUp and \arpeggioWithArrowDown to be really precise.

If you insist on the distinction from things like \slurUp \slurDown, a
comparable situation could be \upbow \downbow. So how about \uparpeggio
\downarpeggio?

My term 'lilypondish' was not related to the name but to the fact that
the tweaked arpeggios are written as postfix and do not need to surround
the note.

Cheers,
Joram

I think my solution addresses the [OP’s] issue without abandoning the 
[existing] benefit: by defining \arpU and \arpD as single-use commands (i.e., 
tweaks), you can still use \arpeggioUp or \arpeggioDown to establish a holding 
direction change.

Yes?

Kieren.

Yes, you do. They change the direction of the entire grob, not the 
arpeggio-direction indicated by the arrow.

Surely it is a question of priorities. Do such alternating patterns

in a while, but each change holds for several subsequent chords? That’s

More imprecise, really. It’s really only the direction of the arrow

That was also discussed in the old thread. Not conclusive but with more
insights than I have:

Is this a case where attaching an arpeggio to a chord with ^ or _ should make a 
difference, or do I misunderstand the point of those characters?

I think at first it was just a property that could be set with an
override. Then this was put into a command for convenience

Yes, that works perfectly. No need to use a function, of course. That 
was just my first approach to solve this problem.

Thanks Malte and Kieren!

Hi Caio,

> I'm trying to write a function

Well, if you *really* want a music function, I’ll let others answer.

But to solve your particular issue, I’d do the following:

  SNIPPET BEGINS
\version "2.19.36"

arp = -\arpeggio
arpU = \tweak arpeggio-direction #UP -\arpeggio
arpD = \tweak arpeggio-direction #DOWN -\arpeggio

\relative c' {
  1\arpU
  1\arpD
  1\arp
}
  SNIPPET ENDS

Hope that helps!
Kieren.
