The "Brass Section" refers to a group of musical instruments made of brass, typically found in orchestras and bands. Common instruments in this section include the trumpet, trombone, French horn, and tuba. These instruments produce sound by buzzing the lips into a mouthpiece, and they are known for their powerful and bright tones. Brass instruments are often used to add richness and depth to musical compositions. They can play both melody and harmony, making them versatile in various genres, including classical, jazz, and marching band music. The brass section plays a crucial role in creating dynamic and vibrant soundscapes.
