[2][1] He was trained as a classical pianist in London, but chose to dedicate his life to the development of culture in the Bahamas.
Under his direction, the new nation of the Bahamas learned an appreciation of its indigenous music.
He co-wrote and directed the Independence Pageant, a survey of Bahamian history from pre-Columbian days to Bahamian Independence from Britain, which was performed on the evening leading up to the morning of July 10, 1973.
Bethel's MA thesis in ethnomusicology, Music in The Bahamas: its Roots, Rhyme and Personality, covered the development of Bahamian music from the slave era to the 20th century, and one chapter of that thesis was expanded into the book Junkanoo: Festival of The Bahamas (Macmillan Caribbean 1992, ISBN 0-333-55469-8).
His daughter, Nicolette Bethel, has continued his work and expanded Junkanoo: Festival of The Bahamas.
