Question: Information:  - Canton is a city in and the county seat of Stark County, Ohio, United States. Founded in 1805 alongside the Middle and West Branches of Nimishillen Creek, Canton became a heavy manufacturing center because of its numerous railroad lines. However, its status in that regard began to decline during the late 20th century, as shifts in the manufacturing industry led to the relocation or repositioning of many factories. After this decline, the city's industry diversified into the service economy, including retailing, education, finance and healthcare.  - Lake Erie is the fourth-largest lake (by surface area) of the five Great Lakes in North America, and the thirteenth-largest globally if measured in terms of surface area. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is deep. Lake Erie's northern shore is bounded by the Canadian province of Ontario, with the U.S. states of Ohio, Pennsylvania, and New York on its southern and easternmost shores and Michigan on the west. These jurisdictions divide the surface area of the lake by water boundaries. The lake was named by the Erie people, a Native Americans people who lived along its southern shore. That Iroquoian tribe called it ""Erige"" "("cat")" because of its unpredictable and sometimes violently dangerous nature. It is a matter of conjecture whether the lake was named after the tribe, or if the tribe was called ""Erie"" because of its proximity to the lake.  - Downtown Cleveland is the central business district of the City of Cleveland and Northeast Ohio, United States. It is the economic and symbolic center of the Cleveland-Akron-Canton, OH Combined Statistical Area. As of 2000, 100,000 people worked in the district; as of 2012, it contained more than 16 million square feet of rentable office space.  - The Lettermen is an American male pop vocal trio.

While elements of rock and roll can be heard in blues records from the 1920s and in country records of the 1930s, the genre did not acquire its name until the 1950s.  - In music, an arrangement is a musical reconceptualization of a previously composed work. It may differ from the original work by means of reharmonization, melodic paraphrasing, orchestration, or development of the formal structure. Arranging differs from orchestration in that the latter process is limited to the assignment of notes to instruments for performance by an orchestra, concert band, or other musical ensemble. Arranging "involves adding compositional techniques, such as new thematic material for introductions, transitions, or modulations, and endings... Arranging is the art of giving an existing melody musical variety".  - A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China and Taiwan.

The city is located on the southern shore of Lake Erie, approximately west of the Pennsylvania border. It was founded in 1796 near the mouth of the Cuyahoga River, and became a manufacturing center owing to its location on the lake shore, as well as being connected to numerous canals and railroad lines. Cleveland's economy has diversified sectors that include manufacturing, financial services, healthcare, and biomedical. Cleveland is also home to the Rock and Roll Hall of Fame.  - Soul music (often referred to simply as soul) is a popular music genre that originated in the United States in the late 1950s and early 1960s. It combines elements of African-American gospel music, rhythm and blues and jazz.

The O'Jays made their first chart appearance with `` Lonely Drifter '' in 1963 , but reached their greatest level of success once Gamble & Huff , a team of producers and songwriters , signed them to their Philadelphia International label in 1972 .

The subtle sound of a vibraphone can often be heard in the background of Philly soul songs. The genre laid the groundwork for disco and what are now considered quiet storm and smooth jazz by fusing the R&B rhythm sections of the 1960s with the pop vocal tradition, and featuring a slightly more pronounced jazz influence in its melodic structures and arrangements.  - Smooth jazz is a popular genre of music that grew out of jazz and is influenced by rhythm and blues, funk, rock and roll, and pop music styles (separately, or, in any combination). Musicians such as Kenny G, Ramsey Lewis, Dave Koz, and Spyro Gyra have had hits with instrumental recordings, while singers such as Anita Baker, Sade, Sting and Norah Jones have found success with vocal releases. George Benson remains a popular Smooth Jazz artist as both a singer and guitar player.  - Funk is a music genre that originated in the mid- 1960s when African American musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and rhythm and blues (R&B). Funk de-emphasizes melody and chord progressions used in other related genres and brings a strong rhythmic groove of a bass line played by an electric bassist and a drum part played by a drummer to the foreground. Funk songs are often based on an extended vamp on a single chord, distinguishing them from R&B and soul songs, which are built on complex chord progressions. Funk uses the same richly-colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths.  - Quiet storm is a radio format and a subgenre of contemporary R&B music that is characterized by understated, mellow dynamics, slow tempos, and relaxed rhythms.

Mather Maritime Museum, the USS "Cod", Burke Lakefront Airport, Voinovich Bicentennial Park, and the Cleveland-Cuyahoga County Port Authority. It is served by the West 3rd and North Coast stations on RTA's light rail Waterfront Line.  - Rhythm (from Greek , "rhythmos", "any regular recurring motion, symmetry" ) generally means a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions" . This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years.  - Disco is a genre of dance music containing elements of funk, soul, pop, and salsa. It achieved popularity during the mid-1970s to the early 1980s. Its initial audiences in the U.S. were club-goers from the gay, African American, Italian American, Latino, and psychedelic communities in Philadelphia and New York City during the late 1960s and early 1970s. Disco can be seen as a reaction against both the domination of rock music and the stigmatization of dance music by the counterculture during this period. It was popular with both men and women, from many different backgrounds.  - Philadelphia International Records (PIR) is an American record label based in Philadelphia.

In 1986, Cleveland was chosen as the hall of fame's permanent home. Since opening in September 1995, the "Rock Hall"  part of the city's redeveloped North Coast Harbor  has hosted more than 10 million visitors and had a cumulative economic impact estimated at more than $1.8 billion.  - Ahmet Ertegun (Turkish spelling: Ahmet Ertegün; ( December 14, 2006) was a Turkish-American businessman, songwriter and philanthropist.  - Atlantic Recording Corporation (simply known as Atlantic Records) is an American record label founded in October 1947 by Ahmet Ertegün and Herb Abramson.
