小號，小提琴，色士風

Saxophone is a woodwind instrument; it's always been mistaken as a brass instrument because of the body material. Be more specific, it's a single reed instrument.

Main components are Mouthpiece, neck, and body. A mouthpiece that can be rubber or metal produces sound and sound is produced by the vibration of the reed that attached to the mouthpiece by a ligature.

Saxophone has to families, Eb Bb and C F.
Nowadays a saxophone quartet includes Bb soprano, Eb Alto, Bb Tenor, and Eb Bariton. Though, Bb bass can be found in a few wind ensemble works.

Famous pieces include Glazounov Concerto for alto saxophone and string orchestra, which is a 15 minute concerto that has no movements but three main parts. The begining part is in moderate tempo and follows by a short fast section, second parts begins slow again and leads to the third part that has a candenza in it. Toward the end, the piece reaches it's peak point but calm down right before the exciting ending. It's written in 1936.

Tempo, keys, and dynamic changes throughtout the piece, composer well use the relationships between the key of Ab and E. He made very smooth transition between these two keys by the commond tones, usually D#(Eb).

Another is Escapades from the DreamWorks film Catch Me if You Can by John William.It's a 3 movement concerto. Fast-Slow-Fast. I am sure most people know about this story. The first movement is about his youth life, second movement is about his dad's death, last is about his capture.
