<P> The song is written in the key of A major . The structure of the composition is in an expanded variation of the AABA pop song format, with eight bars of verse and eight bars of chorus forming the A section, and a nine - bar primary bridge forming the B section . The sustained A chord over the verses creates an implied drone common in Indian music and supports a melody that author Ian MacDonald terms "raga - like". </P> <P> The song's coda features a change of tempo . In the view of musicologist Walter Everett, the latter section marks a progression on previous Beatles songs that similarly revisit aspects of a composition when ending with a coda . In the case of "Ticket to Ride", the section consists of a repeated refrain similar to the last line of the chorus ("My baby don't care"), played over a constant A major chord and set to the double - time rhythm used in the bridge . Lennon said this closing section was one of his "favourite bits" in the song . He also claimed that "Ticket to Ride" was the first heavy metal record ever made . According to MacDonald, the track's heavy sound may have been influenced by Lennon and George Harrison's first encounter with LSD, the precise date for which varies among Beatles biographers . </P> <P> While the lyrics describe a girl "riding out of the life of the narrator", the inspiration of the title phrase is unclear, as is the meaning of the song . McCartney said the title referred to "a British Railways ticket to the town of Ryde on the Isle of Wight", and Lennon said it described cards indicating a clean bill of health carried by Hamburg prostitutes in the 1960s . The Beatles played in Hamburg early in their musical career, and a "ride" was British slang for having sex . Gaby Whitehill and Andrew Trendall of Gigwise have interpreted the song to be about a woman leaving her boyfriend to become a prostitute . </P> <P>--John Lennon, 1970 </P>
