Source-derived summary

The janggu (Korean: 장구, also transliterated as janggo or changgo) or seyogo (세요고; 細腰鼓; lit. 'slim waist drum') is a drum often used in traditional Korean music. It consists of an hourglass-shaped body with two heads made from various types of leather. The two heads produce sounds of different pitch and timbre, which when played together are believed to represent the harmonious joining of Um and Yang. The janggu is one of the four components of samul nori (사물놀이), alongside the buk (북), jing (징) and kkwaenggwari (꽹과리).

History

The earliest depictions of the instrument were inscribed on a bell belonging to the Silla (57 BC–935 AD) period and in a mural painting of the same period in Goguryeo (37 BC–668 AD) tomb. The oldest written records about an hourglass-shaped drum may be traced to the reign of King Munjong (1047–1084) of Goryeo as a field instrument. The Korean record from 1451 titled Goryeo-sa, or History of Goryeo, in chapter 70, records twenty janggu as the gifts of instruments to be used in the banquet attended by the Song dynasty emperor Huizong to the Goryeo court in Gaeseong in 1114. This book also notes the earliest appearance of the word janggu in a Korean source. Later in chapter 80, for the year 1076, the term janggu-opsa (one who plays or teaches the janggu) is used.

Editorial summary

This brief starts where responsible research should: with the source description of “Janggu” as type of Korean drum. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1047, 1084, 1451, 1114—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Janggu, type and Korean can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as type of Korean drum. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q1062015. The Library of Congress control number is sh85022517. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1047, 1084, 1451 and 1114.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
