iterate.naive

abjad.tools.iterate.naive(expr, klass)

Yield left-to-right instances of klass in expr.

Treat expr as an undifferentiated tree; ignore threads.

abjad> container = Container(Voice(construct.run(2)) * 2)

                        a'8
                }
                \context Voice = "vocie 2" {
                        b'8
                        c''8
                }
        >>
}
abjad> for x in iterate.naive(staff, Note):
...     x
... 
Note(c', 8)
Note(d', 8)
Note(e', 8)
Note(f', 8)
Note(g', 8)
Note(a', 8)
Note(b', 8)
Note(c'', 8)

The important thing to notice here is that the function yields notes with no regard for the threads in the which the notes appear.

Compare with iterate.thread().
