“I once asked Ben Britten what he thought was the most important requisite in composing opera. I was sure he would say a sense of drama, ability to indicate the meaning of a scene musically in a matter of seconds. What he said was that the most important thing a composer must have is the ability to write many kinds of music–chorus alone, chorus with orchestra, soloists separately, soloists in ensemble, and so on. The needs are so varied that one must have terrific facility to handle them all.”
Aaron Copland, Copland Since 1943
