It&#8217;s common to end phrases with a descending figure. We do the same thing in common speech to indicate a period at the end of a sentence. To indicate a question mark, we end the sentence by rising in pitch. We also? Do the rising pitch thing? When we uptalk? Like valley girls?\u00a0Rakim&#8217;s phrases in &#8220;Follow The Leader&#8221; gradually rise in pitch, not at the end but all the way through.
