Final answer:
The relationship between spiritual conversion and jazz composition in the late 1960s and early 1970s is represented in the works of Alice Coltrane and Mary Lou Williams.
Step-by-step explanation:
In the late 1960s and early 1970s, spiritual conversion played a significant role in jazz composition, particularly in the works of Alice Coltrane and Mary Lou Williams. Both Coltrane and Williams were deeply influenced by their spiritual journeys and incorporated elements of spirituality into their compositions.
Alice Coltrane, the wife of renowned jazz saxophonist John Coltrane, embraced a spiritual path rooted in Eastern philosophy and Hinduism. She explored concepts of spirituality, transcendence, and cosmic consciousness in her music. Her album 'Journey in Satchidananda' is a great example of her spiritual approach to jazz composition.
Mary Lou Williams, on the other hand, underwent a spiritual conversion to Catholicism in the early 1950s and later became a Roman Catholic. Her faith greatly influenced her compositions, as she blended elements of jazz with religious themes. Her works, such as 'Mary Lou's Mass' and 'Black Christ of the Andes,' reflect her spiritual exploration through jazz.
