<P> The song is in Am, with a shift to a ♭ 7 (Am / G) on "all" (bass note G) and a 6 (D (major 3rd F ♯)) after "love" (bass note F ♯) to a ♭ 6 (Fmaj) on "sleeping" (bass note F). This 8--♭ 7--6--♭ 6 progression has been described as an Aeolian / Dorian hybrid . </P> <P> Everett notes that the change from the minor mode verse (A--B) to the parallel major for the bridge might express hope that "unrealized potential" described in the lyrics is to be "fulfilled", but that the continued minor triads (III, VI and II) "seem to express a strong dismay that love is not to be unfolded". Clapton's guitar contribution has been described as making this a "monumental" track; particularly notable features include the increasing lengths of thrice - heard first scale degrees (0: 17--0: 19), the restraint showed by rests in many bars then unexpected appearances (as at 0: 28--0: 29), commanding turnaround phrases (0: 31--0: 33), expressive string bends marking modal changes from C to C ♯ (0: 47--0: 53), power retransition (1: 21--1: 24), emotive vibrato (2: 01--2: 07), and a solo (1: 55--2: 31) with a "measured rise in intensity, rhythmic activity, tonal drive and registral climb". </P> <Ul> <Li> George Harrison--double - tracked vocals, backing vocal, acoustic guitar, twelve - string guitar, Hammond organ </Li> <Li> Paul McCartney--harmony vocal, piano, bass </Li> <Li> John Lennon--electric guitar with tremolo </Li> <Li> Ringo Starr--drums, tambourine, castanets </Li> <Li> Eric Clapton--lead guitar (uncredited) </Li> </Ul> <Li> George Harrison--double - tracked vocals, backing vocal, acoustic guitar, twelve - string guitar, Hammond organ </Li>
