Definition of embouchure

The word "embouchure" originates from the French language, where it is derived from the word "bouche," meaning "mouth." In the context of music, an embouchure refers to the position and shape of a musician's lips, facial muscles, and teeth while playing a brass instrument, such as the trumpet or trombone. The term "embouchure" was first used in the 16th century to describe the instrument-playing technique. It is believed to have been borrowed from the medical field, where "embouchure" referred to the shape and position of the mouth and lips. In the 18th century, composers and musicians began to pay closer attention to the way players formed their embouchure, recognizing its impact on tone quality and overall sound. Today, a good embouchure is considered essential for any brass instrumentalist, and is taught and practiced throughout a musician's career.
