Final answer:
The statement that all brass instruments are made out of brass is false, as the term 'brass instruments' refers to the sound production method rather than the material composition, and they can be made with various materials including nickel silver and plastics.
Step-by-step explanation:
The statement that all brass instruments are made out of brass is false. While brass alloys have long been employed in musical instruments due to their acoustic properties, not all instruments that are considered part of the brass family are made exclusively of brass. Brass is an alloy typically composed of copper and zinc, and while it is commonly used for instruments like trumpets and trombones, manufacturers sometimes use other materials such as nickel silver or plastics for certain parts of the instrument or for student models due to cost, weight, or durability factors. Furthermore, the term 'brass instruments' is more about the method of sound production (vibration of the lips) than the material they are made of.
The composition of bronze is different from brass, as it is made primarily from copper with the addition of tin and sometimes other metals. Bronze was historically used for making weapons and helmets, as well as for some musical instruments before brass became more common. Even though brass instruments are named for the brass alloy, their construction over time has included a variety of materials selected for their specific properties.
