The trombone is one of the oldest instruments in use today, and has changed very little since its invention in the 1400s. Trombones are members of the brass family, and unlike other band instruments, trombones are operated using a slide. In addition to having a long history, trombones are also very versatile instruments. Trombones are important in symphony orchestras, wind bands, and in a number of styles including salsa, jazz, Broadway, ska, soul, and sacred music. Trombones can also range in tone from soft and angelic to dark and scary.
