The flute is a member of the woodwind instrument family, while the trumpet is a brass instrument. Flutes are typically made of metal, such as silver, gold, or platinum, and they are constructed with a cylindrical tube with a series of holes that are covered with keys or pads. Trumpets, on the other hand, are made of brass and are constructed with a conical tube that flares out at the end. They have valves that are used to change the pitch of the instrument.
The different materials and construction of the flute and trumpet result in different sounds. The flute produces a soft, mellow sound, while the trumpet produces a bright, powerful sound.
