(For those that are not sure, Richard Strauss is not the same composer as Johann Strauss II, who composed the famous Blue Danube. Johann Strauss the first is the second's famous father who also wrote many well-known waltzes and polkas. But Richard is not related at all to the other two famous namesakes.)
(Movie buffs will note that Kubrick also chose Johann Strauss II for the beautiful waltz that so well accompanied the weightless excursions of Dr. Haywood R. Floyd on his flight to the moon.)
I decided to try to analyze what makes this opening so universal.
