A rackett is a double-reed musical instrument, dating from the 16th Century [Grove 20:719]. It has a compact body in which multiple air columns are drilled and joined, thus achieving the low notes of a bassoon in a very small space. No examples of the rackett have been found in medieval armory. For related charges, see hautboy.
Stefan von der Heide bears: Argent semy of musical notes sable, on a pale gules a rackett Or.
