The German composer, Balthasar Resinarius, is possibly, but not certainly, identified with Balthasar Harzer or Hartzer. He took holy orders and became Bishop of Laipa in Bohemia, about 1543. He had been a chorister under Isaac in Maximilian I's court chapel. He became a Catholic priest in the service of Hans von Salhausen, but was an early convert to Lutheranism and an important member of the first generation of Protestant composers.
Georg Rhau issued in Wittenberg in 1543, Balthasar Resinarius' Responsorium numero orctoginta de tempore et festis… libri duo. These 80 responsories were Latin pieces aimed at the Lutheran schools, and he was generously represented in Rhaw's chorale collection of 1544 by some thirty settings, on the whole conservative in their cantus firmus style, imitative writing, and old-fashioned (under-third) cadences. One of these works is a Te Deum for two choirs in alternation.
