I was thinking later.... What about those very first notes? What if those 8ths are meant to be 8ths, in the space of one quarter note, while it's in 2/2? And did that performer do that? Are they longer, just a bit, or is that a nuance?It's kind of the same at the end? Quarter rest? Or the value of a quintuplet?
I do agree.. the editor should have put brackets with proper note values..
Personally I wouldn't mind.
