Construction

The erke is composed of two or more lengths of cane joined at the ends to form a single tube. The internal nodes of the canes are removed and the exterior is often wrapped with gut or wool. The end often has an amplifier made of cow horn or brass. The instrument is blown through at the other end, and may be three to seven metres in length.

The erke has no reed in its mouthpiece, with the tongue of the player fulfilling this role as it is inserted into the side-hole of the tube.
