 In the middle of the second chorus , the " funereal brass " is introduced , stressing the ominous lyrics . After three verses and four choruses , the line " Strawberry Fields Forever " is repeated three times , and the song fades out with guitar , cello , and swarmandal instrumentation . The song fades back in after a few seconds into the " nightmarish " ending , with the Mellotron playing in a haunting tone – one achieved by recording the Mellotron " Swinging Flutes " setting in reverse – scattered drumming , and Lennon murmuring , after which the song completes .
