This is called figure....it can be in many forms/styles and most likely it is part of some crotch area. That's a very pretty piece. With ash and most open grain lumber figure is usually not as pronounced, especially the marbly curly type of figure you have there. If possible , I'd see if I could find the other 2-3 boards.
GREAT find!!! IF you finish right , the curls will POP in brilliancy, most of us call it chautouncy (spelling???)....a deep look.
