FYI..one of my favorite movies is "The Horse Soldiers"..the John Ford epic of the Civil War..about a Union raid into the deep south. Ford always used music in his films ( i.e. "She wore a Yellow Ribbon" and in THe Horse Soldiers, he used authentic instruments and arrangements...There is one scene, where the very young cadets from the military academy are marching off to attack the Union troops, you can here the unique "sound"...it's very special...
I never saw that film. I’ll have to look for it.
