The Trombone is a wind instrument of the trumpet family. It consists of a cylindrical tube, a mouthpiece and a slide, which the musician moves back and forth. This action adjusts the length of the tube, and produces the Trombone’s characteristic glissando sound. Due to its unique construction, the Trombone is the one wind instrument able to produce all tones on the sound spectrum. The Trombone was created around 1450, when the first Trumpet with an adjustable tube made its appearance in Burgundy. By the 16th century, Trombones were made in five different ranges, from high to contrabass. From the late 19th century onwards, the instrument’s triumphant and majestic style made an alto/tenor/bass trio of Trombones a standard addition to orchestras. Many major composers, such as Mozart, Beethoven, Wagner, Tchaikovsky, Johan Strauss, to name but a few, have used Trombones in their orchestral pieces. Nowadays, they are also commonly used in military bands. The Trombone is perhaps the only instrument to have undergone so few modifications since it first appeared; most pertained to the tone holes and bell, and resulted in increasing its range.
