The whole question is in the title actually. I'm arranging some songs, and I wonder whether most pianists can play the ninth E–F# by their left hand. In my arrangement it's in the comfortable bass position (E2–F#3 in the scientific notation) and it's in a series of sustained half-notes so no hurry down there.
Will most pianists be able to play it? Is there any standard on what to assume people manage?
