Alessandro Poglietti [Alexander de Poglietti] (1641 - 07/1683), an (Italian, Austrian or Bohemian) Baroque organist and composer of unknown origin. In the second half of the 17th century Poglietti settled in Vienna, where he attained an extremely high reputation, becoming one of Leopold I's favorite composers. Poglietti held the post of court organist for 22 years from 1661 until his death during the Turkish siege that led into the Battle of Vienna. Poglietti is primarily important for his keyboard music, particularly Rossignolo (1677), a collection of diverse pieces for harpsichord that includes a large number of imitations of natural sounds, and a collection of 12 ricercares, which was widely copied during his lifetime.
