However, the parts for one piece may include additional voices and brass
instruments (primarily cornetts and sackbuts) to be added at tuttis in
the cappella tradition, voices doubling original brass parts, an additional
bass-line instrument to accompany instrumental sections, extra voices and
brass instruments in the form of newly-composed parts that would provide
fuller textures at tuttis, or a combination of the
above. Hammerschmidt encourages the addition of cappellen in his preface to the 1656 collection. This presentation will compare the printed parts with the tablature and hand-written parts found in the Bohn collection to demonstrate how the cappella tradition may have been practiced at Breslau.
