Brass instrument Brass instrument 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", literally meaning "lip-vibrated instruments". There are several factors involved in producing different pitches on a brass instrument. Slides, valves, crooks (though they are rarely used today), 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.

Bit mouthpiece in other nations. Seen in many jumping disciplines. Types of Bits: snaffle What it is: Similar to the French-link, except there is a round "ball" on the middle link. Action: double joint reduces the nutcracker effect. The ball tends to concentrate pressure on the tongue. More severe than the French link, less than the Dr. Bristol. Also applies pressure to the lips and bars of the mouth. Materials: Usually stainless steel Use: Rather rare type of mouthpiece, seen in the English disciplines. Permitted in dressage.
