Amelio was on stage as a pianist and ballerina from age six. She was trained in dance, both classical ballet and traditional Spanish and Latin American styles. For the latter, she often utilized castanets. Amelio has developed castanet arrangements to accompany works of such composers as Chopin and Liszt, and has performed them as a guest artist with orchestras in several countries, including the city symphonies of Novosibirsk, Russia and Reutlingen, Germany. She has also developed dance routines to accompany the works of romantic era composers such as Beethoven and Paganini.
Amelio appeared as a dramatic actress in a number of films and television programs in her native Mexico during the 1960s and 1970s. Much of her recent career has been devoted to musical education. She has conducted seminars and master classes on dance and choreography outside Mexico. Her institutional affiliations have included the Choreographic Institute of Beijing and the Ana Pavlova Institute in Moscow.
