Doesn’t work… sorry I didn’t describe it well. I meant a chord with 5 notes on the RH and an arpeggio on the LH… means you have to place 9 fingers on the beat.
But I revisited, and found that with the tempo for that piece, I could probably grab the big octave and play the rest of the arpeggios – in 2 actions…
It just feels strange there because the rest of the piece isn’t meant to be played that way, so I think there is a note in there that shouldn’t have been written, have abandoned this piece since then…
