A '''synthesizer''' is an electronic keyboard instrument capable of imitating the sound of many traditional instruments, and of producing unique musical sounds of its own.  

A '''synthesizer''' is an electronic instrument capable of imitating the sound of many traditional instruments, and of producing unique musical sounds of its own.  

The concept has a long history. The traditional pipe organ has numerous sets of pipes controlled with stops, producing a variety of different tone colors. Some have names like "flute," "strings," "trombone," and even "Vox humana" (human voice).

By the 1990s, digital electronics made it possible for synthesizers to be performance instruments, playing chords and supplying effect such as vibrato in real time. Improved synthesis algorithms and the use of "sampled" sounds recorded from real instruments made it possible for synthesizers to produce not only electronic sounds but extremely convincing imitations of traditional instrument sounds. In performances of works such as musical comedies and operettas, a sole synthesizer player could produce a tolerable rendition of the score all by himself; not as good as a real 15-piece pit band, of course, but far better than a pianist playing a "piano reduction" of the score.
