to be favored for different styles. Early mouthpieces were designed to produce a "warm" and "round" sound for classical playing. Among classical mouthpieces, those with a concave ("excavated") chamber are more true to Adolphe Sax's original design; these provide a softer or less piercing tone favored by the Raschèr school of classical playing. Saxophonists who follow the French school of classical playing, influenced by Marcel Mule, generally use mouthpieces with smaller chambers for a somewhat "brighter" sound with relatively more upper harmonics. The use of the saxophone in dance orchestras and jazz ensembles from the 1920s onward placed emphasis on dynamic range and projection, leading to innovation in mouthpiece designs. At the opposite extreme from the classical mouthpieces are those with a small chamber and a low clearance above the reed between the tip and the chamber, called high baffle. These produce a bright sound with maximum projection, suitable for having a sound stand out among amplified instruments. Mouthpieces come in a wide variety of materials including vulcanized rubber (sometimes called hard rubber or ebonite), plastic and metals like bronze or surgical steel. Less common materials that have been used include wood, glass, crystal, porcelain and bone. Recently, Delrin has been added to the stock of mouthpiece materials. The effect of mouthpiece materials on tone of the saxophone has been the subject of much debate. According to Larry Teal, the mouthpiece material has little, if any, effect on the sound, and the physical dimensions give a mouthpiece its tone color. There are examples of "dark" sounding metal pieces and "bright" sounding hard rubber pieces. The extra bulk required near the tip with hard rubber affects mouth position and airflow characteristics. History Early development and adoption The saxophone was designed around 1840 by Adolphe Sax, a Belgian instrument maker, flautist, and clarinetist. Born in Dinant and originally based in Brussels, he moved to Paris in 1842 to establish his musical instrument business. Before working on the saxophone, he made several improvements to the bass clarinet by improving its keywork and acoustics and extending its lower range. Sax was also a maker of the ophicleide, a large conical brass instrument in the bass register with keys similar to a woodwind instrument. His experience with these two instruments allowed him to develop the skills and technologies needed to make the first saxophones. As an outgrowth of his work improving the bass clarinet, Sax
