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
Bit mouthpiece Many of the double-jointed bits (especially the French link and Dr. Bristol) are occasionally "added to" by twisting the cannons of the mouthpiece. This increases the severity of the bit, as these cannons act directly on the tongue and bars in addition to the regular action of the bit. A relatively "kind" French mouth can therefore be turned into a severe bit when the cannons are twisted or if the mouthpiece is put onto a gag bit. All references below are based on the cannons being smooth, not twisted. Types of Bits: snaffle, gag, pelham, curb (including driving bits) What
