Ernst Krenek
Newly discharged, Mancini entered the music industry. In 1946, he became a pianist and arranger for the newly re-formed Glenn Miller Orchestra, led by 'Everyman' Tex Beneke. After World War II, Mancini broadened his skills in composition, counterpoint, harmony and orchestration during studies opening with the composers Ernst Krenek and Mario Castelnuovo-Tedesco.
