The Khmer Empire, which flourished between the 9th and 15th centuries in Southeast Asia, was renowned for its cultural sophistication, particularly in the arts. Music was deeply embedded in Khmer society, serving both ceremonial and recreational purposes. Instruments of the Khmer Empire were intricately tied to the religious, cultural, and everyday life of its people. They were used in temples, at royal courts, during performances, and in homes, reflecting the empire’s spiritual and social structure.
Types of Instruments and Their Characteristics
Khmer musical instruments fell into four main categories: percussion, string, wind, and metallophones. Each category included a variety of instruments, often crafted with remarkable artistry.
Percussion Instruments
- Roneat (Xylophones)
The roneat was a key percussion instrument used in Khmer music, particularly in the pinpeat ensemble, which accompanied religious and royal ceremonies. The instrument featured wooden or bamboo bars of varying lengths arranged on a boat-shaped frame. These bars were struck with mallets to produce a resonant, melodic sound.- Materials: Roneat bars were typically made from hardwood or bamboo, while the frame was carved from wood. The mallets had a padded head to create a soft but vibrant tone.
- Sound: It produced a warm, percussive melody with a clear, ringing timbre that complemented other ensemble instruments.
- Occasions: Roneat was played during religious rituals at Angkor Wat and other temples, in dance dramas, and at royal court events.
- Skor Thom (Large Drums)
The skor thom were massive drums played in pairs, essential for maintaining rhythm in Khmer ensembles.- Materials: These drums had a wooden or hollowed-out tree trunk body with animal skins stretched across the ends.
- Sound: They produced deep, booming tones that conveyed authority and grandeur.
- Occasions: Skor thom drums were used in ceremonies and festivals to summon divine attention or mark significant moments.
- Chhing (Hand Cymbals)
The chhing were small, hand-held cymbals that produced sharp, clinking sounds.- Materials: Made of bronze or brass, these instruments were durable and resonant.

Historical Context of Khmer Instruments
Khmer musical traditions were heavily influenced by Indian culture, evident in the structure of the pinpeat ensemble, similar to Indian temple orchestras. Instruments such as the roneat and kong vong thom also bear resemblance to those used in other Southeast Asian cultures, hinting at cultural exchanges between the Khmer Empire and neighboring regions.
The materials used in instruments, such as bronze and hardwood, reflect the empire’s wealth and access to resources. Khmer carvings, including the famous bas-reliefs at Angkor Wat, depict musicians playing many of these instruments, showcasing their integral role in society.
