Brunette Girl With The Sax

The saxophone consists of an approximately conical tube of thin metal, most commonly brass and sometimes plated with silver, gold, and nickel, flared at the tip to form a bell. At intervals along the tube are between 20 and 23 tone holes of varying size, including two very small 'speaker' holes to assist the playing of the upper register. These holes are covered by keys (also known as pad cups), containing soft leather pads, which are closed to produce an airtight seal; at rest some of the holes stand open and others are closed. The keys are controlled by buttons pressed by the fingers, while the right thumb sits under a thumb rest to help keep the saxophone balanced. The fingering for the saxophone is a combination of that of the oboe with the Boehm system, and is very similar to the flute or the upper register of the clarinet. Instruments that play to low A have a left thumb key for that note.
The simplest design of saxophone is a straight conical tube, and the sopranino and soprano saxophones are usually of this straight design. However, as the lower-pitched instruments would be unacceptably long if straight, for ergonomic reasons the larger instruments usually incorporate a U-bend at or slightly above the third-lowest tone hole. As this would cause the bell of the instrument to point almost directly upwards, the end of the instrument is either bevelled or tilted slightly forwards. This U-shape has become an iconic feature of the saxophone family, to the extent that soprano and even sopranino saxes are sometimes made in the curved style even though this is not strictly necessary. By contrast, tenors and even baritones have occasionally been made in the straight style. Most commonly, however, the alto and tenor saxophones incorporate a curved 'crook' above the highest tone hole but below the top speaker hole, tilting the mouthpiece through 90 degrees; the baritone, bass and contrabass extend the length of the bore mainly by double-folding this section.
