Richard: If all the well informed people haven't flooded you with information let me offer you some more. I am a Civil War reenactor and there are several sources of music available. Let's adress the instruments first. All of the instruments we take for granted today with the exception of electric ones existed 140 years ago. While it would have been unusual to see soldiers carrying guitars or even fiddles on the march, in camp behind the lines guitars and such could be rented. The individual soldier carried mouth organ(Harmonica), tin whistles, fifes and the ever present Jaw harp. Almost all regiments had drummers assigned to them, and it was a safe bet you could find a fair number of men who played the bones. Also, without radio, the people in those days wqere not adverse to singing. As to the music, I recommend Kent Courtney, the Second South Carolina String Band and Bobby Horton You migfht also look into Ritchie Haven's stuff and a singer by the name of Sparky Rucker for the African-American music in vogue then. For Sheet music , Jerry Silverman's Folk Music Encyclopedia Vol. 1&2, Mel Bay puts out several books of Folk Music and there is also the Civil War Songbook compiled by Richard Crawford. Three songs that were sung and are under represented in Civil War music books: "The Girl I Left Behind me" was the favorite marching song for the Regulars (The standing army of 1861, "The Bonny Light Horseman" dates to the Napoleonic wars and was brought over by English and Irish immigrants and in the Navy on both sides the sea chantey "Santy Anno was popular(Remember the Mexican War had only been over for 13 years at the start of the Civil War.
