A brass aerophone is a [[musical instrument]] that produces sound by [[Sympathetic resonance|sympathetic vibration]] of air in a tubular [[resonator]] in sympathy with the vibration of the player's lips. Brass instruments are also called ''labrosones'', literally meaning "lip-vibrated instruments".<ref>{{cite book|last = Baines|first = Anthony|title = Brass instruments: their history and development|publisher = Dover Publications|year = 1993|page = 300|isbn = 0-486-27574-4}}</ref> There are several factors involved in producing different [[Pitch of brass instruments|pitches on a brass instrument]]. Slides, [[valve]]s, crooks, or keys are used to change vibratory length of tubing, thus changing the available [[harmonic series (music)|harmonic series]], while the player's [[embouchure]], lip tension and air flow serve to select the specific harmonic produced from the available series. Unlike all other aerophones, brass instruments can be "[[Mute (music)|muted]]", in other words, their sounds can be somewhat suppressed as one would use a [[Silencer (firearms)|silencer]] on a firearm. A variety of mutes exist for these instruments, ranging from those made of plastic to others made of metal, and in various shapes.
