Brass instrument an organ or a choir. 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
Musical technique instrumentals. Different instruments require varying techniques. For example, string instruments require fingering technique, while bowed string instruments require bow technique. Brass and woodwind instruments require mouthing techniques (correct positioning and shaping of the mouth and proper breathing), while woodwind instruments often require fingering technique, brass instruments often have simpler fingering than woodwinds but require a basic understanding of the harmonic series. Musical technique is often related to physical memory, such as correct position and stopping on a string instrument, positioning of the trombone slide, memorizing guitar chords' and piano chords' fingering, and the proper position and shape of one's mouth
