Straight cornetts, which have separate mouthpieces, and mute cornetts, whose mouthpieces are built right into the instrument, are individually turned on the lathe. They receive the same meticulous attention as the curved instruments, and have an easily maintained oil finish. Maple instruments are stained to enhance the beauty of the wood.
A variety of select, well-seasoned hardwoods are used, normally rock maple and black cherry. German plum and Central American boxwood, especially fine woods, are recommended for solo instruments. The curved and straight cornetts are provided with an "acorn" mouthpiece made from horn. Trumpet players doubling on cornett may request a cushioned-rim mouthpiece made from acrylic material.Because each instrument is made to order, special requirements can be accommodated.
