John Baldwin (d. 1615) was a singer and music scribe, affiliated with St. George’s Chapel, Windsor, and later with the Chapel Royal, who copied more than 400 pieces of music. He had a special liking for old, obscure, complex, and politically unfashionable pieces; much of his energy as a copyist was spent on what his own generation would have considered “early music.” As a result, he rescued some of Tallis’s most important works (especially Latin-texted works) from oblivion or near-oblivion. This chapter takes a detailed look at a number of pieces by Tallis in Baldwin’s collection, including the psalm-motets, the Lamentations, and big responsories such as the six-voice Videte miraculum.
