Glissando refers to a rapid ascending or descending scale. It is played differently by different instruments.
For piano or harp, a glissando does not produce the sound of each semitone, as the fingers only move over the white keys on the piano or the available scales on the harp.
For string instruments (such as the violin or erhu), each semitone is produced as the finger moves up or down the position of the string or by pressing each note individually.
For brass instruments, excluding trombone, the fingers must press each note individually. The trombone, however, does not have a key mechanism, and performing a glissando involves controlling the length of the slide.
The common abbreviation for Glissando is "Gliss."

Ludwig van Beethoven, German composer, the predominant musical figure during the transition between the Classical to Romantic eras. He occupies an unprecedented dominance in the history of Western music history, and has been widely regarded as the greatest, most influential and most popular musician who ever lived.
Beethoven's music inherited the artistic atmosphere of Haydn and Mozart, penetrated the desire for dignity, vented the anger tortured by fate, and demonstrated his determination to fight with fate.
Compared to other musicians, Beethoven is effectively to interact the philosophy of life with audience through music. Although he was not a romantic, he had become the object followed by other romantics.
As a musician, Beethoven suffered from ear diseases. However, he was unwilling to succumb to fate, vowing to take fate by the throat, and continue to complete his career. In the last ten years of his life, without hearing any sound, his compositions influenced the development of music for nearly two hundred years.
