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.
It has no musical connections (just to prevent people from converging on this otherwise creative path)
If you'd allow me to modify the image to show irrelevant changes. It doesn't change the reasoning or the answer.
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.
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.
Leaf colors have been already mentioned. Is that all?
I did something to the question that the answer hardly does, everybody here wants a part of the question.
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.
How many different shapes do you see?
