Is there no musical repetition here
While there are no note-pattern repetitions in here, when listening to this - as music - I hear repeated ideas. An appoggiatura (short-long) motif is heard multiple times, as is the upward motion through the keyboard.
This is a neat illustration of the problem of identifying music with its notation. Equating music with a sequence of note onsets, because this is how it looks on the page.
