Brass instrument the player of a brass instrument has direct control of the prime vibrator (the lips), brass instruments exploit the player's ability to select the harmonic at which the instrument's column of air vibrates. By making the instrument about twice as long as the equivalent woodwind instrument and starting with the second harmonic, players can get a good range of notes simply by varying the tension of their lips (see embouchure). Most brass instruments are fitted with a removable mouthpiece. Different shapes, sizes and styles of mouthpiece may be used to suit different embouchures, or to more easily produce certain tonal
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
