It is when you are dealing with two or more cultures. For example, a businessperson might have to use cross-cultural skills to do business in Japan. Cross cultural is a comparison of a culture with one or more other cultures. the purpose is to provide detailed information about the development of others in their own cultures and compare this developemnt across cultures. The comparison looks at not only what is different between the cultures, but also what is similar or universal among them. It always examines the culture from within, viewing the context of that culture, rather than from outside of the culture. This gives true insight into the culture and a truer comparison thus broadening ones appreciation of that culture and of your own.

Excellent question, thank-you for letting me answer it; that's a great big 'NO' 'Cross-cultural' is a meaningless nonce word invented as a 'buzzword' purely as a deliberate attempt at ersatz erudition. The prefixes 'inter', meaning among or between and 'intra' meaning on the inside or within, serve completely to describe cultures, or anything else. Intracultural means inside a single culture, or Intra-anything else. Intercultural means between differing cultures, or Intra-anything else. 'crosscultural' is a self-indulgent bit of academic licentiousness.
Jazz emerged in the early 20th century as a fusion of African American musical traditions, European harmonies, and Latin rhythms, reflecting a rich tapestry of cultural influences. Its roots in blues and ragtime showcased the African American experience, while the incorporation of European instruments and forms helped it gain broader appeal. Additionally, jazz served as a platform for collaboration among diverse musicians, breaking down racial barriers and fostering a sense of community across cultural divides. This cross-pollination of styles and ideas not only enriched the genre but also promoted social change and understanding in a segregated society.
