Another motet section from Simon Boyleau’s 1544 book. “Genuit puerpera” is the 2a pars of the Christmas text “O Magnum misterium”. “Genuit ouerpera” is from an antiphon sung at Lauds on the Nativity (see LU 386) for the plainsong with a slightly different text. It is a literal intabulation and very complex and difficult for performance, although Daza has made the intabulation for an instrument in D, exploiting the full range of the vihuela and showing a very proficient knowledge in the process of intabulation..
