Sweelinck, Jan Pieterszoon

Jan Pieterszoon Sweelinck (1562-1621) was a Dutch composer, organist, and pedagogue whose work straddled the end of the Renaissance and beginning of the Baroque eras.
He was born in Deventer and died in Amsterdam. Many of his family were musicians—principally organists—and he is known to have studied with Jan Willemszoon Lossy as well as Zarlino, composer and theorist, in Venice.

Sweelinck represents the highest development of the Dutch keyboard school, and indeed one of the highest pinnacles attained in keyboard contrapuntal complexity and refinement before J.S. Bach. However, he was a skilled composer for voices as well, and composed over 250 works for voice (chansons, madrigals, motets and psalms). Some of Sweelinck's innovations were of profound musical importance, including the fugue—he was the first to write an organ fugue which began simply, with one subject, successively adding texture and complexity until a final climax and resolution, an idea which was perfected at the end of the Baroque era by Bach. Stylistically Sweelinck's music also brings together the richness, complexity and spatial sense of the Gabrielis, with whom he was familiar from his time in Venice, and the ornamentation and intimate forms of the English keyboard composers. In formal development, especially in the use of countersubject, stretto, and organ point (pedal point), his music was far beyond the works of Frescobaldi—his nearest predecessor—and looks ahead to Bach.

Sweelinck was a master improviser, and acquired the informal title of the "Orpheus of Amsterdam." Over 70 keyboard works of his have survived, and many of them may be similar to the improvisations that residents of Amsterdam around 1600 were likely to have heard. Even his vocal music, which is more conservative than his keyboard writing, shows a striking rhythmic complexity and an unusual richness of contrapuntal devices.

As a teacher, his influence was perhaps as great as it was as a composer, since his pupils included the great North German school, including Praetorius, Scheidemann, Siefert, and Samuel and Gottfried Scheidt. He was known in Germany as the "maker of organists" and was clearly in demand as a teacher.

His influence was international: for example, some of his music appears in the Fitzwilliam Virginal Book, which otherwise mainly contains the work of English composers. Sweelinck wrote variations on John Dowland's internationally famous Lachrimae Pavan, and John Bull, the English keyboard composer, wrote a set of variations on a theme of Sweelinck, indicating the close connection between the different schools of composition across the English Channel.
