The morin khuur (Mongolian: морин хуур ), also known as the horsehead fiddle, is a traditional Mongolian bowed stringed instrument.
 It is one of the most important musical instruments of the Mongol people, and is considered a symbol of the Mongolian nation.
 The morin khuur is one of the Masterpieces of the Oral and Intangible Heritage of Humanity identified by UNESCO.
The bolombatto is a traditional stringed instrument that features in the music of West Africa.
 It consists of four strings, stretched over a gourd, which serves as a resonator.
 The strings each have a different thickness.
 The thickness of it determines how low the sound will be.
 For example, a string that is really thick has a low sound and a really thin string as a high-pitched sound.
 In addition, the instrument also has a tin rattle attached to its body, which the musician plays by striking the strings and gourd simultaneously, adding an element of percussion to the music.
 In this way, it is similar to the "sinding".
The rebec (sometimes rebecha, rebeckha, and other spellings, pronounced or ) is a bowed stringed instrument of the Medieval era and the early Renaissance era.
 In its most common form, it has a narrow boat-shaped body and 1-5 strings.
 Played on the arm or under the chin, the technique and tuning may have influenced the development of the violin and the extended technique of bowed banjo.
The rabel (or arrabel, robel, rovel) is a bowed stringed instrument from Spain, a rustic folk-fiddle descended from the medieval rebec, with both perhaps descended from the Arab rabab.
 The instrument generally has two or three strings of gut or steel, or sometimes twisted horse-hair.
 The instrument is first mentioned in the 12th century, and it is still used in parts of Latin America, as well as the Spanish provinces of Cantabria and Asturias.
The tro sau thom (ទ្រសោធំ; or tro sau) is a bowed stringed instrument from Cambodia.
 It is made from black wood but more basic materials were used, such as a hollow bamboo and a tortoise shell.
 It is used in Cambodian classical music.
The vielle is a European bowed stringed instrument used in the Medieval period, similar to a modern violin but with a somewhat longer and deeper body, three to five gut strings, and a leaf-shaped pegbox with frontal tuning pegs, sometimes with a figure-8 shaped body.
Enkhjargal Dandarvaanchig (Mongolian: Дандарваанчигийн Энхжаргал , born 1968, Ulaanbaatar), also known as Epi, is a Mongolian musician, overtone singer, and Morin khuur player.
 He works in the style of fusion between modern and traditional music.
In music, a double stop refers to the technique of playing two notes simultaneously on a bowed stringed instrument such as a violin, a viola, a cello, or a double bass.
 In performing a double stop, two separate strings are bowed or plucked simultaneously.
 Although the term itself suggests these strings are to be fingered (stopped), in practice one or both strings may be open.
The khushtar (Chinese: 胡西它尔; Uyghur: خۇشتار, Хуштар) is a bowed stringed instrument from the Uyghur Region, Western China.
 It has 4 strings in 4 courses and is tuned G, D, A, E.
The xiqin () was a bowed string musical instrument.
 It is perhaps the original member of the "huqin" family of Chinese and Mongolian bowed string instruments; thus, the "Erhu" and "Morin khuur" and all similar fiddle instruments may be said to be derived from the "xiqin".
 The "xiqin" had two silk strings and was held vertically.
