D'Artega studied music and composition at Strassberger's Conservatory in St. Louis, Missouri with Boris Levenson, who was a pupil of Nikolai Rimsky-Korsakov.
He became a well-known conductor on stage and on air, and in 1946 initiated the Carnegie Hall "Pops" concerts with members of the New York Philharmonic.
As a result of that success, the group was booked by the newly formed United Service Organization (USO) Camp Shows.
For the 1973 film Fifty Years of Thorns and Roses, a documentary about saint, priest, and mystic Padre Pio of Pietrelcena, Alfonso D'Artega composed and copyrighted the score.
