Tera de Marez Oyens was a Dutch composer. De Marez Oyens was born in Velsen as Woltera Gerharda Wansink. She studied at the Conservatorium van Amsterdam with a major in piano, studying the instrument with Jan Odé, and graduated in 1953. Here, her talent for composition was discovered as she wrote her first pieces. These included chamber music and song cycles. After that she came in contact with youth groups, for whom she also wrote individual pieces. She then became the cantor of the Reformed church community of Hilversum. Because of this she was very busy with church music. She wrote 14 melodies for the church songbooks that appeared in 1973. The lyrics for these songs were supplied by, among others, Muus Jacobse, Willem Barnard and Ad den Besten, whom she knew personally. She wrote the melody for "Zolang er mensen zijn op aarde" by Huub Oosterhuis. In the 1960s she became interested in electronic music, and studied with Gottfried Michael Koenig at the Institute of Sonology in Utrecht. Sound and Silence and Mixed Feelings are pieces of electronic music she composed, and Pente Sjawoe is an example of a work in which the tone poem plays an important role.
