The Brass Family refers to a group of musical instruments that produce sound through the vibration of air in a tubular structure. Common instruments in this family include the trumpet, trombone, French horn, and tuba. They are typically made of brass or other metals and are played by buzzing the lips into a mouthpiece. Brass instruments are known for their bright, powerful sound and are often used in orchestras, bands, and various music genres. They can produce a wide range of pitches by altering the length of the tubing, either through valves or by sliding a slide, as seen in the trombone.
