Hip Hop Jazz funk is a hybrid of hip-hop and jazz dance. This style is used by artists like Beyoncé. Although it borrows from hip-hop dance, it is not considered a style of hip-hop because the foundational movements are jazz.
In hip-hop – even in lyrical hip-hop – there are no pirouettes or arabesques and you do not dance on relevé. However, these methods are used in jazz funk and in jazz dance in general.
