Consider the following screenshot:
As you can see, the piece ends with an arpeggio that starts on the bass staff and ends on the treble staff. As I understand it, the best and clearest way to notate this is with a cross-staff arpeggio line, as I’ve written. However, I also use the sustain pedal throughout the piece, including on the final notes, and as you can see, the cross-staff arpeggio line is intersecting the pedal line (Sibelius detects this collision and colors the conflicting line red).
What is the proper way to notate this? Should I write two short arpeggio lines, one on each staff, and add some other marking to make clear they’re meant to play as one continuous arpeggio?
