In the concert hall I see more and more musicians & singers replacing paper music sheets with 12” iPad Pro’s. Mostly individual artist but recently all members of a cappella choir. Some, eg the violinists, use a small device on the floor probably connected by Bluetooth to advance to the next page with their foot. I don’t remember seeing a conductor with the full score on an iPad though, maybe one day with a foldable 2x20+”.
