Well, here's a chance to plug American 19th century popular music: Many military posts had small bands that played quicksteps, quadrilles, polkas, schottisches, galops, waltzes,redowas (& ever popular transcriptions from whatever opera was in style) for the local community as well as for military events..

Here are some good CD's true to the period: For American Civil War: "Union and Liberty" CD (Dorian) by D.C. Hall's New Concert & Quadrille Band. (string band)

Another good string group: Hesperus

Also, check out Brass Band music such The American Brass Quintet Brass Band CD "The Yankee Brass Band",the Chestnut Brass Company & Friends CD "Listen to the Mockingbird", and finally Eastman Wind Ensemble & Chorale's CD "Homespun America"
