Chorales Deconstructed, v.1 (Coy) [2 to 4 trombones]
Set of 13 Bach Chorales in settings for one, two, three or four trombones. Each chorale is written out four times. A nice way to build these works from the foundation melody, adding the bass line and finally the chordal realization. Published in score form (you will need at least 2 copies to perform with a trio or quartet unless your group is comfortable at close quarters).
