context_page_description: A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called labrosones or labrophones, from Latin and Greek elements meaning 'lip' and 'sound'.
  There are several factors involved in producing different pitches on a brass instrument. Slides, valves, crooks, or keys are used to change vibratory length of tubing, thus changing the available harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produced from the available series.
  The view of most scholars is that the term "brass instrument" should be defined by the way the sound is made, as above, and not by whether the instrument is actually made of brass. Thus one finds brass instruments made of wood, like the alphorn, the cornett, the serpent and the didgeridoo, while some woodwind instruments are made of brass, like the saxophone.
context_section_description: A few specialty instruments are made from wood.
  Instruments made mostly from plastic emerged in the 2010s as a cheaper and more robust alternative to brass. Plastic instruments could come in almost any colour. The sound plastic instruments produce is different from the one of brass, lacquer, gold or silver. While originally seen as a gimmick, these plastic models have found increasing popularity of the last decade and are now viewed as practice tools that make for more convenient travel as well as a cheaper option for beginning players.
