Arnoldus Christiaan Vlok van Wyk (26 April 1916 – 27 March 1983) was a South African art music composer, one of the first notable generation of such composers along with Hubert du Plessis and Stefans Grové.
Arnoldus Christiaan Vlok van Wyk was born on 26 April 1916 on the farm Klavervlei, not far from Calvinia, a small town in the Northern Cape province of South Africa. He was the sixth of eight children. His mother, Helena van Dyk, came from a wealthy family seemingly descended from the seventeenth century court painter Anthony van Dyck. The couple married when farming provided reasonable hopes of financial security, however Van Wyk's father was never an efficient manager of the business. Little is known about his childhood other than that life was difficult. From as early as 1918, the family struggled financially, his father Arnoldus Christiaan Vlok van Wyk abused his wife and children. Several members of the family, including Van Wyk's mother and eldest sisters, demonstrated musical talent but had little opportunity for musical education.
Van Wyk took occasional piano lessons from his 'favourite" sister Minnie and soon he was "improvising dramatic piano illustrations of stories told by anyone soft-hearted enough to pay him sixpence." At 16, Van Wyk was sent to boarding school at Stellenbosch Boys' High School in Stellenbosch. He took piano lessons first from the cellist Hans Endler and later from Miss C.E. van der Merwe. His mother died in Somerset Hospital in Cape Town, followed a few weeks later by the death of his eldest sister. He matriculated at the age of seventeen and decided to spend the next year preparing for an overseas piano scholarship, an effort that proved unsuccessful. He took a job in Cape Town in the claims department at an insurance company. During this time, he made contact with Charles Weich, music critic of the Afrikaans newspaper Die Burger, who invited him to perform for the first time at a concert of works "by unknown South African composers" hosted by the Oranjeklub. It brought an audience to Van Wyk's works and provided the young composer with a voice.
In 1938, Van Wyk began studies aimed at a BA-degree at the University of Stellenbosch. He interrupted his studies to study at the Royal Academy of Music in London. He was the first South African composer to receive a Performing Right Scholarship to study there, initially granted for one academic year. Van Wyk received permission to continue his studies there until 1944. While studying at the Royal Academy, Van Wyk received many prizes, including the 1941 Worshipful Company of Musicians Medal, awarded to the most distinguished student in the Academy. Van Wyk had many concerns about his first professional training from his composition teacher, Theodor Holland. After a few months at the Royal Academy, Van Wyk wrote in a letter:
