A chorus reed of 4' pitch, essentially an octave Trumpet. The word Clarion is also used as a modifier for a variety of reed stops (not all of them chorus reeds) to indicate a stop of octave pitch; for example Oboe Clarion. The name Trompette Clarion, mentioned only by Irwin in a stoplist in his entry for Trompette Harmonique, is an inappropriate combination of French and English; nevertheless, it has been used in at least one organ (see examples below).
