The right ending is an open door you can't see too far out of. It can mean exactly the opposite of what you are thinking.
Michael Ondaatje Coming Through Slaughter
Earlier this week I was making a rough recording of a piece when I made a mistake at the ending. I heard the possibility of this new ending. Played the piece with the new ending a couple times and decided to be open to the change. The next day I played the piece for my wife with each ending. Just two notes changed but there was a distinctive difference in the affect of the piece. The new ending gives a clear musical ending while the original offers something just a bit beyond. Took a little time to decide, but I'm leaving the ending alone.
