1. Xylophone
1.1 Ranad ek (ระนาดเอก in Thai)
This is an instrument many people in the world know well about. It has 21 or 22 wooden bars(Mostly 22), suspended by two ropes over boat-shaped resonator. Typically made from rosewood (Thai: ไม้ชิงชัน; Mai ching chan) or bamboo. Each bar is tuned by a lump of lead and beewax mixture, stuck under the head and the end of a bar (Ranad tum, which I'm going to introduce, is tuned in this way,too). It is played by two types of mallets; hard and soft. There is a counterpart of this instrument in Cambodia called ronaet ek and in Laos called nang nad ek.
Ranad ek is the leading instrument of the pipat (ปี่พาทย์) and mahori (มโหรี).
