How does the first scence in Act 1 of Macbeth capture audiences' attention?This is in the scottish play/ Macbeth

The opening scene of Macbeth not only
captures our attention but it also seems to strike the key-note of the
play.

1) The scene captures our attention because it is
laid in "a desert place", barren and eerie-looking, away from human
habitation;

2) The three witches appear in adverse weather,
amidst thunder and lightning, the adversity of weather presumably born of their
incantation, an adversity which is more supernaturally conjured up, rather than
natural;

3) The "weird sisters" look alien and intent on
some evil mission, and they speak of a future meeting with Macbeth on a
"heath";

4) The witches converse in a strangely stylized
manner and in an enigmatic, paradoxical language;

5) The
most captivating aspect of the scene is, however, the anarchical formula that they chant
in chorus: "fair is foul, and foul is fair", a formula that strikes
the key-note to the whole play.
