Vulcan brass or truba ("trumpet") is a popular genre, especially in the central and southern Serbian origin of Vulcan brass. The tradition of music comes from the first Serbian riot. The trumpet was used as a military tool for collecting soldiers and announcing battles by waking up, but since the soldier used it to populate popular folk songs, the trumpet played an interesting role. When the war was over and the soldiers came back to country life, the music entered the civilian life and eventually became a music style with birth, baptism, wedding ceremonies and funeral. There are mainly two types of this type. One is from Western Serbia and the other from South Serbia.
