A brass band is made up of instruments that are all played by blowing air through a metal mouthpiece, creating a vibration that travels through the metal tubing and comes out as a musical note. By pressing valves or moving a slide, the player changes the length of the tubing and therefore the pitch of the note. The bigger the instrument, the lower and deeper the sound it makes.
Monaco's brass band tradition is closely connected to the Carabiniers du Prince — the small, ceremonial guard of Monaco's royal family. The band members wear smart uniforms and perform at events including the changing of the guard at the palace, Monaco National Day on 19 November, and Sainte Dévote Day in January. Their performances are a familiar and beloved part of life in Monaco.
Brass bands have a long history going back several hundred years, when marching bands played to coordinate soldiers and announce important events. Today, the tradition is about music and celebration rather than anything military. Many children in Monaco learn brass instruments at school, and joining a band is a popular activity.
