This essay discusses Calvin's perspectives on music. Calvin's writings published between 1536 and 1543 are chosen as the main area for investigation. The essay examines how the writings were put into practice in Psalters by analysing the two psalms which were collected in Calvin's first Psalter Aulcuns psaulmes et cantiquesmys en chant published in 1539. At the same time the content and development of the Genevan Psalter in French language is examined as well.
