The soundtrack for the 1959 film black orpheus introduced which latin style to european and north american audiences?

In the 1959 Black Orpheus soundtrack, the Latin style which was introduced to the European and North American audiences is the Bossa Nova. This originated in Brazil and incorporated elements of USA jazz. It was considered a new Brazilian popular style with a lyrical fusion between samba and jazz. This is slang for "something new and different" or "new trend". This was popularized in the 1950s and 1960s. Today, this is considered as one of the best-known Brazilian music genres. This genre is usually played or performed with nylon-string classical guitar, played with fingers rather than a pick. If one wants to hear its purest form, unaccompanied guitar with vocals is one sure way to see or hear it performed.
