What are no reed instruments made of?

No reed instruments, such as flutes and brass instruments, are typically made from materials like metal, wood, or synthetic substances. Flutes are often crafted from silver, gold, or various types of wood, while brass instruments like trumpets and trombones are made from brass alloys. Additionally, some modern instruments may use plastics or other synthetic materials to enhance durability and sound production. These materials contribute to the unique tonal qualities and playing characteristics of each instrument.
