HOW ACAPPELLA STARTED 90s

Acapella largely develops in places where instruments aren't easy to get, which obviously explains why slaves in the US caused a major development in modern acapella music. By bringing over African concepts of call-and-response that you can see in my post regarding ladysmith black mambazo and combining them with European ideas of harmony and structure and religion, we get the development of negro spirituals that later lead to what we now know as gospel. Like most things, white people got their grubby hands on black music, so these are mostly white interpretations on black spirituals. which weren't anywhere near as complex as these links. I can't find legit acapella spirituals, so these will have to do (#7, #8). And here's some gospel: (#9, #10).

In singing words, some a cappella singers also emulate instrumentation by reproducing instrumental sounds with their vocal cords and mouth. One of the earliest 20th century practitioners of this method was The Mills Brothers whose early recordings of the 1930s clearly stated on the label that all instrumentation was done vocally. More recently, "Twilight Zone" by 2 Unlimited was sung a cappella to the instrumentation on the comedy television series Tompkins Square. Another famous example of emulating instrumentation instead of singing the words is the theme song for The New Addams Family series on Fox Family Channel (now ABC Family). Groups such as Vocal Sampling and Undivided emulate Latin rhythms a cappella. In the 1960s, the Swingle Singers used their voices to emulate musical instruments to Baroque and Classical music. Vocal artist Bobby McFerrin is famous for his instrumental emulation. A cappella group Naturally Seven recreates entire songs using vocal tones for every instrument.
The Swingle Singers used nonsense words to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Like the other groups, examples of their music can be found on YouTube. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella also. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements.^[57] Petra Haden used a four-track recorder to produce an a cappella version of The Who Sell Out including the instruments and fake advertisements on her album Petra Haden Sings: The Who Sell Out in 2005. Haden has also released a cappella versions of Journey's "Don't Stop Believin'", The Beach Boys' "God Only Knows" and Michael Jackson's "Thriller". In 2009, Toyota commissioned Haden to perform three songs for television commercials for the third-generation Toyota Prius, including an a cappella version of the Bellamy Brothers 1970s song "Let Your Love Flow".^{[citation needed]}
Christian rock group Relient K recorded the song "Plead the Fifth" a cappella on its album Five Score and Seven Years Ago. The group recorded lead singer Matt Thiessen making drum noises and played them with an electronic drum machine to record the song.
The German metal band van Canto uses vocal noises to imitate guitars on covers of well-known rock and metal songs (such as "Master of Puppets" by Metallica) as well as original compositions. Although they are generally classified as a cappella metal, the band also includes a drummer, and uses amplifiers on some songs to distort the voice to sound more like an electric guitar.
    Everyone knows about Africa's incredible concepts of rhythm - we see it all the time in jazz and other music that co-opts it. but a big deal in South Africa is a genre known as Isicathamiya (literally pronounced isi-*click*a-ta-mee-ya). Influenced by another form of acapella South African music called Mbube, which I admit I know nothing about, Isicathamiya involves a chorus singing extremely close harmony. A lot of it call and response, in which the lead of the group sings or says a phrase, and the group as a whole responds with a sung refrain, which exists in almost every folk culture. Isicathamiya ups the ante by many times introducing choreography into the mix. Perhaps the most famous example of Isicathamiya is the inimitable ladysmith black mambazo, first introduced to the world stage by Paul Simon on his album Graceland. Ladysmith is literally so good that they're banned from Isicathamiya competitions in South Africa - they're allowed to perform, but they can't compete. Africa as a whole I'm sure has lots of acapella music, but Isicathamiya holds the largest popularity, and is the most I know on the subject. I loved ladysmith ever since I heard graceland, and I have a couple of their albums (#4    Nowadays, acapella music is considered mostly fringe music, but the desires still exist - groups that typically use instruments will at least a couple times indulge in the joy of acapella arrangements (#12, #13), but if you take the time to look, acapella music can be beautiful, stirring, and just as capable as instrumental music at evoking emotions.Also in Nigeria acappella is the most populous music genre especially AKWA IBOM STATION,which UBONG IKPEH has brought everybody to the limelight of acappella music.....
