Images and recordings are supplied where available; note that there are often variations within a national musical tradition, and thus the images and recordings may not be accurate in depicting the entire spectrum of the given nation's music, and that some images and recordings may be taken from a region outside the core of the national instrument's home when such distinctions have little relevance to the information present in the image and recordings. A number of countries have more than one instrument listed, each having been described as a national instrument , not usually by the same source; neither the presence of multiple entries for one nation, nor for multiple nations for one instrument, on this list is reflective of active dispute in any instance. Alternative names and spellings are given. These mostly come from alternative spellings within English or alternative methods of transliterating from a foreign language to English, such as the Chinese yangqin , also transliterated yang ch'in and yang qin . Others reflect regions or subcultures within a given nation, such as the Australian didgeridoo which is or has been called didjeridu , yidaki , yiraki , magu , kanbi and ihambilbilg in various Australian Aboriginal languages . All non-English words are italicized.
