organist

thumb|right|A cathedral organist in Lausanne Cathedral An organist is a musician who plays any type of organ. An organist may play solo organ works, play with an ensemble or orchestra, or accompany one or more singers or instrumental soloists. In addition, an organist may accompany congregational hymn-singing and play liturgical music.

==Classical and church organists== The majority of organists, amateur and professional, are principally involved in church music, playing in churches and cathedrals. The pipe organ still plays a large part in the leading of traditional western Christian worship, with roles including the accompaniment of hymns, choral anthems and other parts of the worship. The degree to which the organ is involved varies depending on the church and denomination. It also may depend on the standard of the organist. In more provincial settings, organists may be more accurately described as pianists obliged to play the organ for worship services; nevertheless, some churches are fortunate to have trained organists capable of more elaborate "voluntaries" (the solo music before, during and after the service) and improvisation. As most churches can afford to employ only one musician, the organist is usually also responsible for directing and rehearsing the choir(s). In the twentieth-century, many pipe organs were replaced by pipe-less electronic and digital organs, often as a low-cost alternative to rebuilding older pipe organs.
