Chopin's Raindrop prelude, first measure.
The notes marked in red technically do not fit into their group (connected by the beam). If I define two voices however, they will be no longer connected to the beam. There are official editions out there that do separate those two note from the group, but I really prefer the way shown in the picture.
But how would I do this? How do I connect both "wrong" notes to this beam? Can I just fake and override the duration of these notes? I did not find a way to do this. And merging notes – as far as I found – only deals with same notes but different types of heads at the same time.
Edit: As I continued to look for solutions I found a way to fake the duration:
\override NoteHead.duration-log = #1 <des' f'> \revert NoteHead.duration-log
But still: Is there an elegant or correct way to deal with this via voicings?
