請解釋咩係RnB

節奏藍調（Rhythm and Blues, R&B），又稱節奏和藍調、節奏怨曲。是一種首先非裔美國人藝術家所演奏，並融合了爵士樂,福音音樂和藍調音樂的音樂形式。這個音樂術語由是美國告示牌雜誌（Billboard）於1940年代末所提出。
這個術語最初在1947年的美國被公告牌雜誌的Jerry Wexler創造為一個音樂的市場營銷術語[1],取代了種族音樂(最初來源於the black community,但是被戰後的社會認為會令人很不愉快的詞語) and the Billboard category Harlem Hit Parade in June 1949. 這個詞最初被用於定義包含了12種藍調格式and boogie-woogie with a back beat的搖滾音樂，後來這種音樂轉變成了一種rock and roll的基礎元素。

在 「Rock & Roll: An Unruly History」 (1995)中 Robert Palmer 把節奏藍調定義為a catchall rubric 用來refer 任何一種美國黑人創造的音樂。在他1981年出版的 「Deep Blues」中， Palmer 用 "r&b" 作為跳躍藍調的縮寫. Lawrence Cohn, 「Nothing But the Blues」的作者, 寫到節奏藍調是一個umbrella term industry convenience為所發明的, 除了古典音樂和宗教音樂，節奏藍調包括了所有的黑人音樂，除了那是一首福音歌並且其銷售足以打入流行榜。
在1960年代, 節奏藍調被用於總括靈魂和funk音樂的術語。而現在R&B的縮寫差不多一直被用於代替full節奏藍調，參考有迪士高發展而來的現代靈魂和funk影響的流行音樂， 這個詞的主流運用變得不那麼流行

RnB also called R&B (Rhythm and blues) is a popular music genre combining jazz, gospel, and blues influences — first performed by African American artists.The term was coined as a musical marketing term in the United States in 1947 by Jerry Wexler at Billboard magazine. [1] It replaced the term race music (which originally came from within the black community, but was deemed offensive in the more positive postwar world,[2]), and the Billboard category Harlem Hit Parade in June 1949. The term was initially used to identify the rocking style of music that combined the 12 bar blues format and boogie-woogie with a back beat, which later became a fundamental element of rock and roll. In 1948, RCA Victor was marketing black music under the name Blues and Rhythm. The words were reversed by Wexler of Atlantic Records, the leading label in the R&B field in the early years.[3] In Rock & Roll: An Unruly History (1995) Robert Palmer defines "rhythm and blues" as a catchall rubric used to refer to any music that was made by and for black Americans. In his 1981 book Deep Blues Palmer used "R&B" as a synonym for jump blues. Lawrence Cohn, author of Nothing but the Blues, writes that rhythm and blues was an umbrella term invented for industry convenience, which embraced all black music except classical music and religious music, unless a gospel song sold enough to break into the charts. By the 1970s, rhythm and blues was being used as a blanket term to describe soul and funk. Today the acronym R&B is almost always used instead of the full rhythm and blues, and mainstream use of the term refers to a modern version of soul and funk-influenced pop music that originated as disco became less favorable.
