 A half @-@ measure complicates the meter of the verses , as well as the fact that the vocals begin in the middle of the first measure . The first verse comes after the refrain , and is eight measures long . The verse ( for example " Always , no sometimes ... " ) starts with an F major chord in the key of B ♭ ( or E chord in the key of A ) ( V ) , which progresses to G minor , the submediant , a deceptive cadence . According to Alan Pollack , the " approach @-@ avoidance tactic " ( i.e. , the deceptive cadence ) is encountered in the verse , as the leading @-@ tone , A , appearing on the words " Always know " , " I know when " " I think a No " and " I think I disagree " , never resolves into a I chord ( A in A key ) directly as expected . Instead , at the end of the verse , the leading note , harmonized as part of the dominant chord , resolves to the prevailing tonic ( B ♭ ) at the end of the verse , after tonicizing the subdominant ( IV ) E ♭ chord , on " disagree " .
