Christiaan Johannes Nobels (1938 - 2015) was organist of the Canadian Reformed Church in Brampton, Ontario for many years.
Throughout his life he produced a number of simple arrangements for a number of Genevan Psalm melodies, as well as a number of hymns. In addition, just before his death he successfully completed a set of preludes for each of the 150 Genevan Psalm melodies.
