In the latter quarter of the twentieth century, Jaap ter Linden became recognized as one of the leading musicians associated with Baroque music. He helped found the well-known Musica da Camera ensemble and has made numerous recordings, mostly of Baroque repertory, but inclusive of Classical and even modern works. In the twenty-first century he remained active in both the concert hall and recording studio as a cellist, gambist, and conductor. Jaap ter Linden was born in Rotterdam, Holland, on April 10, 1947. He showed talent early on and enrolled at The Hague's Royal Conservatory to study cello. There he advanced quickly and also began playing the viola da gamba, an instrument associated with Renaissance-era and Baroque music. This branching out in music also extended into other academic areas, as ter Linden turned to the study of psychology, a field, however, that would ultimately not divert him from his musical pursuits. In 1966, ter Linden and Ton Koopman co-founded Musica da Camera, a quartet devoted to the performance of Baroque repertory. Thirteen years later he and Koopman again united to found a major ensemble, the Amsterdam Baroque Orchestra, a group in which ter Linden would serve as first cellist. In the 13-year period in between, the ever-active ter Linden had become a member of the Musica Antiqua Köln and the English Concert. It was during his nearly 20-year career with the Amsterdam Baroque Orchestra (1979-1998) that ter Linden's recording activity grew sharply. With this ensemble he recorded much Bach, including the Brandenburg Concertos and numerous cantatas. But ter Linden also appeared in chamber music recordings that featured a variety of works: sonatas by Handel, with Koopman and Marion Verbruggen, for Harmonia Mundi; sonatas and trio sonatas by Buxtehude for Dacapo, where ter Linden played the viola da gamba; and even the popular twentieth century piece Bachiana brasileira No. 5 by Villa-Lobos, for Decca. Later on, ter Linden began focusing on conducting, even founding yet another important ensemble, the Amsterdam Mozart Academy, in 2000. He has led the Deutsche Kammerphilharmonie, Beethoven Academie, the Arnhem Symphony Orchestra, Amsterdam Bach Soloists, and Portland Baroque Orchestra. He holds professorships at The Hague's Royal Conservatory and Wurzburg's Hochschule für Alte Musik, and still devotes time to solo and chamber performances.
