Êđê people call an aerophonic instrument belonging to the freely vibrating reed branch Kypah.

Kypah is popular in the communities of some ethnic groups in Tây Nguyên with many different names. For example, Giarai group call it Tơ Jiếp, Tà ôi people call it Tâng Coi, etc.

Kypah is made of the horn of the buffalo, the ox, or the antelope. People cut a part 26 cm – 34 cm long and open at two ends from the horn. The small end is pierced a rectangular hole 3 cm long and 1 cm wide. After that, the wax is heaped around the hole to the height of 3 cm. One neuhouzeaua reed is attached to it for blowing.

When performing Kypah, two hands of the player raise it and he holds all blowing part in his mouth. After that, he blows a strong or light jet of air into the pipe to create sounds.

The player can use the thumb of his right hand to cover and uncover the small end to create different sounds and his palm slightly claps the big end to create trilling sounds (it depends on that the player is left-handed or right-handed). Kypah has three sounds: Do1 - Re1 - Mi1.

The sound of Kypah is resounding and urging.

Men play Kypah in hunting and informing villagers of big events.
