Hmm. This is a real puzzler, because even though the Beam object
implements the grob-interface, only certain grob properties have any
effect. Specifically, I tried the following on a small test file and
they did nothing:
\once \override Voice.Beam #'X-extent = #'(0 . 15)
\once \override Voice.Beam #'extra-X-extent = #'(0 . 15)
Oddly enough, the following DID have an effect:
\once \override Voice.Beam #'extra-offset = #'(0 . 15)
but of course I can't really imagine any use for this.
Here's an idea:
1. Just beam from the first three notes over to the high G-flat.
2. On the D in the left hand, do a \once \override Voice.Stem
#'flag-style = #'no-flag, and do a \stemUp.
3. On the D in the left hand, do a \once \override NoteColumn
#'force-hshift = #-1. Adjust this value until the stem is aligned
perfectly with the stem of the note in the right hand.
4. On the D in the left hand, do a \once \override Voice.Stem #'length =
#12 or however long it needs to be to meet up with the beam.
I did my research out of the 2.5 manual, so your mileage may vary; but I
don't think there's anything especially late-breaking about any of the
features I used above. The noteheads of the eighth-notes in the left &
right hands won't be horizontally aligned, but their stems will meet the
beam in the same place. Is that acceptable?
