Serpent

Other Names: Bass cornet
Type: Brass (?) or wind
Origin: 1590 A.D., in Auxerre
In Redwall: N/A
Appearance: The bass cornett was certainly a strange looking instrument, the predecessor to the tuba.  It had a brass mouthpiece, deeply cupped, and the wooden body of the instrument was an ever-widening tube in a convoluted, winding shape that prompted the nickname of "serpent." There were six finger holes on the serpent's body, and no thumb holes.  It was usually made from several fairly short pieces joined together and covered with leather; other times, glued up from two complete halves of hollowed out blocks of wood.
Use: The serpent had up to three octaves, and its various pitches were determined by fingerings and by the tenseness of the mouth when the lips were buzzed to create sound.  Flats and sharps were reached by covering a finger hole partway.  It took a lot of practice to get a good sound out of the bass cornet, as every note was dependant on the correct embouchure and pitch accuracy.
