Since it's modern. Look the composer/arranger up and see if you ask them. Unless this is something new and just got standardized I think the composer/arranger should have put an extra explanation in there to help out the performer since it's unusual.
On t'other hand, why bother? The composer\arranger\software couldn't be bothered to write something pianistic so why should we pianists be bothered to make any effort either.Play whatever you want, nicco. That is what I do when presented by something this stupid.Steve
Will do
Well the concert is over, we deicided to go with the single chord closure since the soloist had a long finishing note
