Song structure

orchestra crescendos, and a sustained final piano chord. While Lennon’s lyrics were inspired by contemporary newspaper articles, McCartney’s were reminiscent of his youth. The decisions to link sections of the song with orchestral crescendos and to end the song with a sustained piano chord were made only after the rest of the song had been recorded. A waveform view of “A Day in the Life” showing its characteristic crescendos and sudden instrumental changes. "A Day in the Life" is in the key of G major, but, as Alan W. Pollack explains, "its true center of gravity is in the parallel minor G Major and the Major keys of E". The verses are in G-major/E-minor and the bridge is in E-major. A 4/4 meter is used throughout. The song is laid out with an instrumental beginning, followed by three verses (0:13), an orchestral crescendo (1:45), a middle section (2:16), an orchestral bridge (2:49), the final verse (3:19), a second orchestral crescendo (3:50), and a final piano chord (4:21–5:05). Each verse is sung by Lennon and follows the same basic layout, but each has a different way of ending. The first verse, which is twenty measures, ends with a repetition of the F major chord progression before returning to the home key. The second verse, two measures shorter than the first, ends on the C major chord rather than repeating the F major progression. The third verse is the same as the second, except that there is one more measure (to accommodate the "I'd love to"), and the verse does not return to the home key. Instead it leads to a bridge, a 24-measure long glissando-like crescendo starting from low E to an E several octaves higher. Random cymbal crashes are interspersed near the end to "challenge your sense of meter". An alarm clock rings, beginning McCartney's middle section. While the pulse of this section remains the same, the accents suggest a tempo twice as fast as that of the verses before. The three chords in this nineteen measures long section are the I, flat VII, and V chords (E, D, and B). This is followed by an orchestral bridge: a repeated circle of fifths (from C to E) over twenty measures. The bridge is accompanied by a wordless vocal ("Ahhhh...")There is currently no definitive available reference as to who the vocalist is. and leads to the fourth and final verse. The final verse has the same layout as the third verse. Starr's drumming, however, retains its double-time feel from McCartney's section. This verse leads to the second crescendo. However, after the orchestra hits its highest note, there is a measure of silence, which leads to the final E-major piano chord.

The final chord

chords in music history. Lennon, McCartney, Starr, and Evans shared three different pianos and 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. The piano chord was a replacement for a failed vocal experiment: on the evening following the orchestra recording session, the four Beatles had originally recorded an ending of their voices humming the chord, but after multiple overdubs they found that they wanted something with more impact.
