Kelly's essay focuses upon the major music personalities of the era, the American reception of European classical music, popular songs and dances of the home front and in the camps, the American musical community, African-American music and musicians, military and civilian bands, the music publishing industry, innovations of instruments and the impact of the war on post-war music.
The most popular composers of music during the war were John Hill Hewitt (Confederate) and George Root (Union). Remarkably, Hewitt was a native of NYC, disliked slavery and pro-Union but lived in the South and remained there throughout the war. Working in Richmond he penned the classics Somebody's Darling, and All Quiet Along the Potomac Tonight and many others. Root wrote over 30 songs during the war including The Vacant Chair, The Battle Cry of Freedom, Just Before the Battle, Mother, and Tramp! Tramp! Tramp! . Kelly includes three others in the pantheon. 1.) Thomas Greene Wiggins aka Thomas (Blind Tom) Bethune a music savant who was black, enslaved, blind and unable to care for himself and thought to be an idiot in all things except music, 2.) Patrick Gilmore an Irish immigrant who was an extraordinary band leader, promoter,and who produced monster concerts one of which included a 500 piece band, a 6,000 voice chorus, 50 canons, and 40 soldiers striking anvils and is credited with writing When Johnny Comes Marching Home, and 3.) Clara Louise Kellogg, a professional soloist, opera company manager, native South Carolinian who moved to NYC before the war and lived there during it.
Regarding European influences, the impact travelled both ways across the Atlantic.
Rimsky-Korsakov, later to become one of Czarist Russia premier composers, was in the Russian navy on a shipped stationed off the eastern seaboard of the U.S. He left notes regarding the impact of his Northern visits upon his later composition. For the most part though, it was European opera companies touring the North during the war that schooled American students in performance that influenced American popular culture.
