FamousShe Loves You Sixth ChordShe Loves You, The Beatles, 1963 · The Beatles (Lennon-McCartney); the sixth suggested by George Harrison
The last chord of the song, sung in three-part harmony over the band
She Loves You ends on a G chord with an added E on top, a 'major sixth'. George Harrison suggested it, and George Martin thought it sounded old-fashioned, like a 1940s Glenn Miller big band, but the group kept it. The three voices sing G, D and E over the band's G major. On guitar, a G chord with the top string left open gives exactly those notes.
Also called The Beatles G6 ending, the 'corny' sixth
