A proper understanding of Sullivan's creative stance is central to any discussion of the musical contribution to the Savoy operas. During the course of an interview given to the San Francisco Daily Chronicle in 1885 he made what amounts to a ‘mission statement’ regarding his approach to composition for the stage. ‘I adhere’, he said, ‘to the principles of art which I had learned in the production of more solid works, and no musician who analyses the score of those light operas will fail to find the evidence of seriousness and solidity pointed out’.

The use of the word ‘serious’ does not mean that Sullivan wished his music to be sombre and sad, but that it should be responsive to any stimulus, whether comic or serious – he certainly did not see emotional seriousness as the antithesis of comedy. In addition a central part of his stated seriousness of purpose emerges as a belief in real emotion, which for him was intuitively linked to a sense of humanity. Expressing scepticism towards Italian, French and Wagnerian opera, he rejected the maxim that opera is of life, but larger than it. Rather he was inclined to make emotion not ‘unreal and artificial’ as he put it, but as real as possible – a natural reaction to credible experience. Time after time he ensures that his musical settings remain sympathetic to the characters themselves, giving them a degree of dignity even while embracing their sometimes unpleasant Gilbertian features.
