The instrument has a conical hardwood body with seven finger holes. Unlike its Chinese and Korean counterparts, the kèn bầu has a detachable bell made of jackfruit wood, carved in the shape of a gourd (originally it was probably made out of an actual dried gourd, but wood is more durable). Into the playing end is fitted a small brass tube onto which a small double reed is placed. This type of musical instrument are quite familiar in Asia, the Indian analogy being Shehnai.
