input: World War II brought about a swift end to the big band era as musicians went off to serve in the military and travel restrictions made touring difficult. When the war ended, the focus of popular music shifted towards crooners such as Frank Sinatra and Jo Stafford, so Ellington's wordless vocal feature "Transblucency" (1946) with Kay Davis was not going to have a similar reach. With inflation setting in after 1945, the cost of hiring big bands went up and club owners preferred smaller jazz groups who played in new styles such as bebop. Dancing in clubs also subjected club owners to a new wartime tax which continued for many years after, which made small bands more cost-effective for club owners. Ellington continued on his own course through these tectonic shifts. While Count Basie was forced to disband his whole ensemble and work as an octet for a time, Ellington was able to tour most of Western Europe between April 6 and June 30, 1950, with the orchestra playing 74 dates over 77 days. During the tour, according to Sonny Greer, the newer works were not performed, though Ellington's extended composition, Harlem (1950) was in the process of being completed at this time. Ellington later presented its score to music-loving President Harry Truman. Also during his time in Europe, Ellington would compose the music for a stage production by Orson Welles. Titled Time Runs in Paris and An Evening With Orson Welles in Frankfurt, the variety show also featured a newly discovered Eartha Kitt, who performed Ellington's original song "Hungry Little Trouble" as Helen of Troy. In 1951, Ellington suffered a significant loss of personnel: Sonny Greer, Lawrence Brown, and most importantly Johnny Hodges left to pursue other ventures, although only Greer was a permanent departee. Drummer Louie Bellson replaced Greer, and his "Skin Deep" was a hit for Ellington. Tenor player Paul Gonsalves had joined in December 1950 after periods with Count Basie and Dizzy Gillespie and stayed for the rest of his life, while Clark Terry joined in November 1951. During the early 1950s, Ellington's career was at a low point with his style being generally seen as outmoded, but his reputation did not suffer as badly as some artists. Andre Previn said in 1952: "You know, Stan Kenton can stand in front of a thousand fiddles and a thousand brass and make a dramatic gesture and every studio arranger can nod his head and say, Oh, yes, that's done like this. But Duke merely lifts his finger, three horns make a sound, and I don't know what it is!" However, by 1955, after three years of recording for Capitol, Ellington lacked a regular recording affiliation.

input: In the early 1970s, Corea took a profound stylistic turn from avant-garde to a crossover jazz fusion style that incorporated Latin jazz with Return to Forever. Named after their eponymous 1972 album, the band relied on both acoustic and electronic instrumentation and drew upon Latin American styles more than on rock music. On their first two records, Return to Forever consisted of Flora Purim on vocals, Joe Farrell on flute and soprano saxophone, Airto Moreira on drums , and Stanley Clarke on double bass. Drummer Lenny White and guitarist Bill Connors later joined Corea and Clarke to form the second version of the group, which expanded the earlier Latin jazz elements with a more rock and funk-oriented sound inspired by the Mahavishnu Orchestra, led by his Bitches Brew bandmate John McLaughlin. This incarnation of the group recorded the album Hymn of the Seventh Galaxy, before Connors' departure and replacement by Al Di Meola, who was present on the subsequent releases Where Have I Known You Before, No Mystery, and Romantic Warrior. Corea's composition "Spain" appeared on the 1972 Return to Forever album Light as a Feather. This is probably his most popular piece, and it has been recorded by a variety of artists. There are also a variety of recordings by Corea himself. These included an arrangement for piano and symphony orchestra that appeared in 1999 and a collabration with vocalist Bobby McFerrin on the 1992 album Play. Corea usually performs "Spain" with a prelude based on Joaquin Rodrigo's Concierto de Aranjuez (1940), which earlier received a jazz orchestration on Davis and Gil Evans' Sketches of Spain. In 1976, he issued My Spanish Heart, influenced by Latin American music and featuring vocalist Gayle Moran (Corea's wife) and electric violinist Jean-Luc Ponty. The album combined jazz and flamenco, supported by Minimoog backup and a horn section.

input: Entering the 2011 season, Kaymer turned down a chance to become a full PGA Tour member; he had gained exempt status with his win in the PGA Championship. He stated he would concentrate on the European Tour for 2011, but would play several U.S. events as well. In January, Kaymer claimed his third Abu Dhabi HSBC Golf Championship title in four years and displaced Tiger Woods as number two in the world rankings. After his runner-up finish at the 2011 WGC-Accenture Match Play Championship, Kaymer overtook Lee Westwood as the number one golfer in the world, making him only the second German (after Bernhard Langer) to be the top-ranked golfer in the world. At the time he was the second youngest to reach world number one behind Tiger Woods, soon surpassed by Rory McIlroy in March 2012, who gained the top ranking at age 22. In April, he relinquished his number one ranking after eight weeks to Westwood, who won the Indonesian Masters. After reaching the number one ranking, Kaymer decided to undergo a swing change to be able to move the ball both ways. Frustrated with his disappointing results at the Masters, Kaymer looked to better shape a draw, a shot he thought he needed to be able to contend at Augusta. Kaymer missed the cut at the Masters for the fourth time in 2011 and later admitted that changing his swing for Augusta was a "big mistake." The rest of 2011 was relatively inconsistent for Kaymer. In November 2011, Kaymer won his first WGC title at the WGC-HSBC Champions event in Shanghai, China. He entered the final round trailing Fredrik Jacobson by five strokes, then shot a final round 9-under 63 to take the title by three strokes from Jacobson. After parring his opening six holes, Kaymer birdied nine of the remaining twelve, with four straight birdies at the start of the back nine. This was the biggest comeback win ever in the history of the WGC events, and the lowest final round by a WGC winner, topping a 64 set by Hunter Mahan in 2010. Kaymer became the tenth player to have won both a major and a WGC event, and the win took him back to world number four.
