The pin is a Cambodian harp, one of the most important instruments of the past, now being restored in modern times. Its historical importance is emphasized by the very name for Cambodian classical music, pin-peat. After the pin was no longer being used, Cambodians continued to use the instrument's name for classical music into the present era. When the pin was no longer being used, the tonal range of other instruments was expanded, possibly to compensate. Burmese saung gauk and roneats had more keys for the chromatic scale and the number of gongs in the kong von thom and kong toch "more than doubled in number since the musician depicted on the Angkorian carvings."
The pin may have been introduced to Cambodia since Funan period; however, the earliest surviving depiction of the pin in Cambodia is dated to the 7th century on the temple at Sambor Prey Kuk, the capital of Chenla. The instrument appeared in Hindu religious art in Khmer temples dating back between the 7th and 13th centuries A.D. The instrument was recorded in a bas-relief at Bayon, Cambodia, a Buddhist temple built in the 12th to 13th century A.D. During the Angkor era from the 9th to the 14th centuries A.D., it was still being played in the royal Khmer ensemble. Reasons for its loss are theory. "One idea is that the instrument disappeared because of the development of the melodic percussion orchestra." Another is that the instrument was lost in 1431 during the war that demolished the Angkor civilization. Another is that it was associated with Hindu religion and as the country became Buddhist, it left the instrument behind with the old religion.
Recreation of Historical Khmer Harp
Ethnomusicologist Patrick Kersalé, who has worked in Asia for more than 20 years, studied images left over from the past, "tracing out the shape of the harp." He looked for clues to understand how the harps were used and made. He also looked at similar instruments in the region, such as the Burmese saung gauk and harps of the Kareni people. Kersalé asked Keo Sonan Kavei to help him build the harp. To help the instrument become part of active culture again, Him Sophy began to compose for it. Burmese harp. This is a relative of the Cambodian pin and is similar.
