His chief claim to fame is his contribution to church music . In 1531 he had successfully supplicated at Oxford for the Mus. Doc. degree, submitting in support a number of compositions of church music . One of his compositions, entitled ‘ My love mourneth ,’ had already been included in Wynkyn de Worde 's Bassus ( 1530 ). There is no doubt that he did much by precept and practice to improve the standards of church music , and he holds a high place among Tudor musicians .
But Gwynneth was also active as a controversial writer on behalf of Roman Catholicism . He wrote several books in reply to those of John Frith , the friend and ally of Tyndale , who had been martyred in 1533 , These works show wide learning and a good degree of dialectical skill.
Gwynneth lived on into the reign of queen Elizabeth , and may have suffered imprisonment for refusing to accept the act of uniformity of 1559 . He died probably about 1562 .
