Following the final orchestral climax, the song ends with one of the most famous final chords in music history. Lennon, McCartney, Starr, and Evans shared three different pianos, with Martin on the Harmonium, and all played an E-major chord simultaneously. The final chord was made to ring out for over forty seconds by increasing the recording sound level as the vibration faded out. Towards the end of the chord the recording level was so high that listeners can hear the sounds of the studio, including rustling papers and a squeaking chair.
