Pipe and Tabor
Pipe and Tabor is a pair of instruments, popular since medieval times and played by a single player, consisting of a specially designed fipple flute, the three-hole pipe, played with one hand, and a portable drum played with the other. The pipe consists of a cylindrical tube of narrow bore, pierced with three holes, two in front and one at the back, all very near the end of the pipe; and of a mouthpiece of the kind known as whistle, fipple or beak common to the flûtes à bec or recorder family.
