Although once made of wood, glass or ivory, piccolos today are made from plastic, resin, brass, nickel silver, silver, and a variety of hardwoods, most commonly grenadilla. Finely made piccolos are often available with a variety of options similar to the flute, such as the split-E mechanism. Most piccolos have a conical body with a cylindrical head, which is like the Baroque flute and later flutes before the popularization of the Boehm bore used in modern flutes. Unlike other woodwind instruments, in most wooden piccolos, the tenon joint that connects the head to the body has two interference fit points that surround both the cork and metal side of the piccolo body joint.
