“Brian Wilson’s arrangements on Pet Sounds are so musically complex and meticulous that meaning can be derived at a remarkably technical level, as music critic Jim Fusilli explained in his book about the album:” begins in B major, a key rarely used in pop, and remains in B major. The G# major chord below the first, and only, time the word "love" is invoked in the song is particularly striking; on the second pass, the G# major chord hits below the word "fail." In a rare example of the bassist emphasizing the root in a Brian Wilson arrangement, Carol Kaye hits the G# in both instances. It's as if Brian wanted there to be no confusion for the listener: in his mind, at least in this song, love equals failure."
