My first puzzle of this type. In the following visual design the hidden clues will lead you to the final verbal association. It is only one word.
Hint 1
It has no musical connections (just to prevent people from converging on this otherwise creative path)
Hint 2
If you'd allow me to modify the image to show irrelevant changes. It doesn't change the reasoning or the answer.
Hint 3
Following Hint 2, don't prioritize to interpret the missing parts, but rather focus on what you can really see, to gather as many clues as possible.
Hint 4
The word you can't see (I mean the final solution) can't be "maple", just for the same reason as it can't be "marie", or " varied". Maybe a later hint will clarify this if you don't see what I mean.
Hint 5
Leaf colors have been already mentioned. Is that all?
Hint 6
I did something to the question that the answer hardly does, everybody here wants a part of the question.
Hint 7
Someone requested a hint(/clarification) that describes what was guessed right or wrong. I will try to be as clear as possible. Right(1): The lines refer to letters. Right(2): those letters are the letters of "maple". Right(3): Leaf/Leaves is a relevant remark Right(4): The different coloring is deliberate and important. Wrong: everything else. My advice was: the "cutout" parts are not informative, the visible parts are informative.
Hint 8
How many different shapes do you see?
