 Shaw's collected musical criticism, published in three volumes, runs to more than 2,700 pages. It covers the British musical scene from 1876 to 1950, but the core of the collection dates from his six years as music critic of The Star and The World in the late 1880s and early 1890s. In his view music criticism should be interesting to everyone rather than just the musical élite, and he wrote for the non-specialist, avoiding technical jargon — "Mesopotamian words like' the dominant of D major '". He was fiercely partisan in his columns, promoting the music of Wagner and decrying that of Brahms and those British composers such as Stanford and Parry whom he saw as Brahmsian. He campaigned against the prevailing fashion for performances of Handel oratorios with huge amateur choirs and inflated orchestration, calling for "a chorus of twenty capable artists". He railed against opera productions unrealistically staged or sung in languages the audience did not speak.
