"I Want to Hold Your Hand" is a song by the English rock band The Beatles. Written by John Lennon and Paul McCartney, and recorded in October 1963, it was the first Beatles record to be made using four-track equipment. Lennon and McCartney did not have any particular inspiration for the song. Instead, they had received specific instructions from manager Brian Epstein to write a song with the American market in mind.

"I Want to Hold Your Hand" was the band's first number-one hit on the Hot 100 chart, starting the British Invasion of the United States music charts. The song entered the chart on 18 January 1964 at number 45; it later held the number one spot for seven weeks, and ended up charting for 15 weeks. It also held the top spot in the United Kingdom charts. A million copies of the single had already been ordered on its release. "I Want to Hold Your Hand" became The Beatles' best-selling single worldwide.

Brian Epstein was getting worried about The Beatles' lack of commercial success in America—their earlier singles had flopped there—and so he encouraged Lennon and McCartney to write a song that would appeal to American listeners. McCartney had recently moved into 57 Wimpole Street, London W1, where he was living as a guest of Dr. Richard and Margaret Asher, whose daughter, actress Jane Asher, had become McCartney’s steady girlfriend after meeting him earlier in the year. This location briefly became Lennon and McCartney’s new writing base, taking over from McCartney’s Forthlin Road home in Liverpool. Margaret Asher taught the oboe in a "small, rather stuffy music room" in the basement and it was here that Lennon and McCartney sat at the piano and composed 'I Want to Hold Your Hand'. In September 1980, Lennon told Playboymagazine:

In 1994, McCartney agreed with Lennon's description of the circumstances surrounding the composition of "I Want to Hold Your Hand" saying:

The Beatles started recording "I Want to Hold Your Hand" at Abbey Road Studios in Studio 2 on 17 October 1963. This song, along with the single's flip side "This Boy", was the first Beatles song to be recorded with four-track technology. Both songs were recorded on the same day, and each needed seventeen takes to complete. Also the Beatles were experimenting with organ sounding guitars which was achieved by extreme compression on John Lennon rhythm guitar. Mono and stereo mixing was done by George Martin on 21 October 1963, and further stereo mixes were done on 8 June 1965, for compilations released by EMI affiliates in Australia and the Netherlands, and on 7 November 1966.

"I Want to Hold Your Hand" was one of two Beatles songs (along with "She Loves You" as " Sie liebt dich") to be later recorded in German, entitled "Komm, gib mir deine Hand". Odeon, the German arm of EMI (the parent company of The Beatles' record label, Parlophone Records) was convinced that The Beatles' records would not sell in Germany unless they were sung in German. The Beatles detested the idea, and when they were due to record the German version on 27 January 1964 at EMI's Pathe Marconi Studios in Paris (where The Beatles were performing 18 days of concerts at the Olympia Theatre) they chose to boycott the session. Their record producer, George Martin, having waited some hours for them to show up, was outraged, and insisted that they give it a try. Two days later, The Beatles recorded "Komm, gib mir deine Hand", one of the few times in their career that they recorded outside of London. However, Martin later conceded: "They were right, actually, it wasn’t necessary for them to record in German, but they weren’t graceless, they did a good job".

"Komm, gib mir deine Hand" appeared in full stereo on the US Capitol LP 'Something New' and currently on the new Capitol CD compilation called "The Capitol Albums Vol. I".

The track was a big hit in Germany, but today the English versions are much better known in Germany (The Beatles Red and Blue albums feature the English hits on the German pressings).

In the UK, "She Loves You" (released in August) had shot back to the number one position in November following blanket media coverage of The Beatles (described as Beatlemania). Mark Lewisohn later wrote: “'She Loves You' had already sold an industry-boggling three quarters of a million before these fresh converts were pushing it into seven figures. And at this very moment, just four weeks before Christmas, with everyone connected to the music and relevant retail industries already lying prone in paroxysms of unimaginable delight, EMI pulled the trigger and released 'I Want To Hold Your Hand'. And then it was bloody pandemonium".

On 29 November 1963, Parlophone Records released "I Want to Hold Your Hand" in the United Kingdom, with "This Boy" joining it on the single's B-side. Demand had been building for quite a while, as evidenced by the one million advance orders for the single. When it was finally released, the response was phenomenal. A week after it entered the British charts, on 14 December 1963, it knocked "She Loves You", another Beatles song, off the top spot, the first such instance of the same act taking over from itself at number one in British history, clinging to the top spot for five full weeks. It stayed in the charts for another fifteen weeks afterwards, and incredibly made a one-week return to the charts on 16 May 1964. Beatlemania was peaking at that time; during the same period, The Beatles set a record by occupying the top two positions on both the album and single charts in the United Kingdom.

EMI and Brian Epstein finally convinced American label Capitol Records, a subsidiary of EMI, that The Beatles could make an impact in the United States, leading to the release of "I Want to Hold Your Hand" with "I Saw Her Standing There" on the B-Side as a single on 26 December 1963. Capitol had previously resisted issuing Beatle recordings in the U.S. This resulted in the relatively modest Vee-Jay and Swan labels releasing the group's earlier Parlophone counterparts in the U.S. Seizing the opportunity, Epstein demanded US$40,000 from Capitol to promote the single (the most The Beatles had ever previously spent on an advertising campaign was US$5,000). The single had actually been intended for release in mid-January 1964, coinciding with the planned appearance of The Beatles on The Ed Sullivan Show. However, a 15-year old fan of The Beatles, Marsha Albert, was determined to get hold of the single earlier. Later she said:

James was the deejay for WWDC, a radio station in Washington, D.C. Eventually he decided to pursue Albert's suggestion to him and asked the station's promotion director to get British Overseas Airways Corporation to ship in a copy of "I Want to Hold Your Hand" from Britain. Albert related what happened next: "Carroll James called me up the day he got the record and said 'If you can get down here by 5 o'clock, we'll let you introduce it.'" Albert managed to get to the station in time, and introduced the record with: "Ladies and gentlemen, for the first time on the air in the United States, here are The Beatles singing 'I Want to Hold Your Hand.'"

The song proved to be a huge hit, a surprise for the station, as they catered mainly to a more staid audience, which would normally be expecting songs from singers such as Andy Williams or Bobby Vinton instead of rock and roll. James took to playing the song repeatedly on the station, often turning down the song in the middle to make the declaration, "This is a Carroll James exclusive", to avoid theft of the song by other stations.

Capitol threatened to seek a court order banning airplay of "I Want to Hold Your Hand", which was already being spread by James to a couple of deejays in Chicago and St. Louis. James and WWDC ignored the threat, and Capitol came to the conclusion that they could well take advantage of the publicity, releasing the single two weeks ahead of schedule on 26 December.

The demand was insatiable; in the first three days alone, a quarter million copies had already been sold (10,000 copies In New York City every hour). Capitol was so overloaded by the demand, it contracted part of the job of pressing copies off to Columbia Records and RCA. By 18 January, the song had started its fifteen-week chart run, and on 1 February, The Beatles finally achieved their first number-one in America, emulating the success of another British group, the Tornados with "Telstar", which was number one on the Billboardcharts for three weeks over Christmas and New Year 1962/63. The Beatles finally relinquished the number one spot after seven weeks, passing the baton to the very song they had knocked off the top in Britain: "She Loves You". Hunter Davies's biography of the band states that "I Want to Hold Your Hand" received certification for sales of 5 million copies in the US alone. The replacement of themselves at the summit of the U.S. charts was the first time since Elvis Presley in 1956, with "Love Me Tender" beating out "Don't Be Cruel", that an act had dropped off the top of the American charts only to be replaced by another of their releases.

With that, the "British Invasion" of America had been launched. Throughout 1964, only British artists flew high at the top of the American charts; including The Dave Clark Five, The Rolling Stones, The Kinks, The Hollies and Herman's Hermits.

The American single's front and back sleeves featured a photograph of The Beatles with Paul McCartney holding a cigarette. In 1984, Capitol Records airbrushed out the cigarette for the re-release of the single.

"I Want to Hold Your Hand" was also released in America on Meet The Beatles!, which ground-breakingly altered the American charts by actually outselling the single. Beforehand, the American markets were more in favour of hit singles instead of whole albums; however, two months after the album's release, it had shipped more than three-and-a-half million copies, a little over a hundred thousand ahead of the "I Want to Hold Your Hand" single.

The song was greeted by raving fans on both sides of the Atlantic but was dismissed by some critics as nothing more than another fad song that would not hold up to the test of time. Cynthia Lowery of the Associated Press expressed her exasperation with Beatlemania by saying of The Beatles: "Heaven knows we've heard them enough. It has been impossible to get a radio weather bulletin or time signal without running into 'I Want to Hold Your Hand'."

Bob Dylan was impressed by The Beatles' innovation, saying, "They were doing things nobody was doing. Their chords were outrageous, just outrageous, and their harmonies made it all valid." For a time Dylan thought The Beatles were singing "I get high" instead of "I can't hide". He was surprised when he met them and found out that none of them had actually smoked marijuana.

The song was nominated for the Grammy Award for Record of the Year, but the award went to Astrud Gilberto and Stan Getz for "The Girl from Ipanema". However, in 1998, the song won the Grammy Hall of Fame Award. It has also made the list in The Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. In addition, the Recording Industry Association of America, the National Endowment for the Arts and Scholastic Press have named "I Want to Hold Your Hand" as one of the Songs of the Century. In 2004, it was ranked number 16 on Rolling Stonemagazine's list of the 500 greatest songs of all time. It was ranked number two in Mojo's list on the "100 Records That Changed the World", after Little Richard's "Tutti Frutti". The song was ranked number thirty-nine on Billboard's All Time Top 100"I Want to Hold Your Hand" is currently ranked as the twenty-third best song of all time, as well as the number three song of 1963, in an aggregation of critics' lists at acclaimedmusic.net.

The Beatles' recording of this song also appeared as the opening track in the 1997 Time-Life 6-CD boxed set, Gold And Platinum: The Ultimate Rock Collection.

Starting at the song's final week at #1 on the American charts, The Beatles had a whopping record of seven #1 songs in one year. In order, these were "I Want to Hold Your Hand", "She Loves You", "Can't Buy Me Love", "Love Me Do" (a somewhat out-of-place 1962 re-release), "A Hard Day's Night", "I Feel Fine", and ending with "Eight Days a Week" one year later.

Reminiscent of Tin Pan Alley and Brill Building techniques and an example of modified thirty-two-bar form, the song is written on a two-bridge model, with only an intervening verse to connect them. The song has no real "lead" singer or even a clearly defined melody, as Lennon and McCartney sing in harmony with each other. Lennon's vocals are more prominent on the recording; however, when The Beatles performed the song on The Ed Sullivan Showon 9 February 1964, McCartney's vocals could be heard more clearly (although this may have been due to the audio mix, as their mikes weren't turned to the same sound level).
