Key signature names and translations
When a musical key or key signature is referred to in a language other than English, that language may use the usual notation used in English (namely the letters A to G, along with translations of the words "sharp", "flat", "major" and "minor" in that language): languages which use the English system include Irish, Welsh, Azeri, Hindi, Japanese (based on katakana in iroha order), Korean (based on hangul), Chinese, Thai, Indonesian, Filipino, Swahili, Esperanto.
Swahili language
Swahili, also known as Kiswahili (translation: coast language), is a Bantu language and the first language of the Swahili people.
 It is a lingua franca of the African Great Lakes region and other parts of eastern and south-eastern Africa, including Tanzania, Kenya, Uganda, Rwanda, Burundi, Mozambique, and the Democratic Republic of the Congo (DRC).
 Comorian, spoken in the Comoros Islands is sometimes considered to be a dialect of Swahili, though other authorities consider it a distinct language.
Gweno language
Gweno is a Bantu language spoken in the North Pare Mountains in the Kilimanjaro Region of Tanzania.
 The people known as the Gweno (or more properly "Asu") are a Chaga ethnic and linguistic group.
 Since the Chaga people are Bantu speakers, the adopted language contains dialects similar to that of the Kenyan language Kamba.
 Gweno shares about 54% to 56% of its vocabulary with other Chaga dialects and 46% with Taita dialects.
 However, a large percentage of its vocabulary is not seen in the other dialects.
 Also at the start of the 11th century, the Chaga people descended and migrated from the Bantu group in which they migrated to the foothills of mount Kilimanjaro.
 The Gweno language is today spoken mostly by older adults, with younger generations having shifted to Asu and Swahili.
 "Ethnologue" considers Gweno to be moribund; the language is not being passed down because children have not been exposed to Gweno since the 1970s.
 The generational shift from Gweno to either Asu or Swahili has certainly created shifts in dialect, however Gweno speakers do not see this as a threat. Turu language
The Turu or Nyaturu language, "Kinyaturu", also known as Rimi "Kirimi", is a Bantu language of spoken by the "Wanyaturu" also known as "Arimi" of the Singida region of Tanzania.
 Excluding the Bantu language prefixes "Ke-" and "Ki-," other spellings of the language are "Limi" and "Remi".
 Dialects of the three Turu tribes are "Girwana" of the "Airwana (Wilwana)" in the north, "Giahi" of the "Vahi (Wahi)" in the south and west, and "Ginyamunyinganyi" of the "Anyiŋanyi (Wanyinganyi)" in the east. Mzungu
Mzungu (] ) is a Bantu language term used in the African Great Lakes region to refer to people of European descent.
 It is a commonly used expression among Bantu peoples in Kenya, Tanzania, Malawi, Rwanda, Burundi, Uganda, Democratic Republic of Congo, Comoros, Mayotte and Zambia, dating back to the 18th century.
 Literally translated it meant "someone who roams around" or "wanderer."
 The term was first used in the African Great Lakes region to describe European explorers in the 18th century, apparently as a result of their extensive travelling all over the world.
 The word Mzungu comes from Kiswahili, where "zungu" or "zunguka" is the word for spinning around on the same spot.
 "Kizunguzungu" is Kiswahili for a dizziness.
 The term is now used to refer to "someone with white skin" or "white skin".
 The word Mzungu in Swahili can also mean someone who speaks English.
 A person in Swahili is "Mtu" and "English" in Swahili is "Kizungu" hence the combination of the two words to make up a word "Mzungu." Masaba language
Masaba ("Lumasaaba"), sometimes known as Gisu ("Lugisu") after one of its dialects, is a Bantu language spoken by more than two million people in East Africa.
 Gisu dialect in eastern Uganda is mutually intelligible with Bukusu, spoken by ethnic Luhya in western Kenya.
 "Masaba" is the local name of Mount Elgon and the name of the son of the ancestor of the Gisu tribe.
 Like other Bantu languages, Lumasaba has a large set of prefixes used as noun classifiers.
 This is similar to how gender is used in many Germanic and Romance languages, except that instead of the usual two or three, there are around eighteen different noun classes.
 The language has a quite complex verb morphology. Kirundi
Kirundi, also known as Rundi, is a Bantu language spoken by 9 million people in Burundi and adjacent parts of Tanzania and the Democratic Republic of the Congo, as well as in Uganda.
 It is the official language of Burundi.
 Kirundi is mutually intelligible with Kinyarwanda, an official language of Rwanda, and the two form part of the wider dialect continuum known as Rwanda-Rundi. Nyakyusa language
Nyakyusa, or Nyakyusa-Ngonde, is a Bantu language of Tanzania and Malawi spoken by the Nyakyusa people around the northern end of Lake Malawi.
 There is no single name for the language as a whole; dialects are Nyakyusa, Ngonde (Konde), Kukwe, Mwamba (Lungulu), and Selya (Salya, Seria) of Tanzania.
 Disregarding the Bantu language prefixes "Iki-" and "Ki-," the language is also known as Konde ~ Nkhonde, Mombe, Nyekyosa ~ Nyikyusa, and Sochile ~ Sokili. Ha language
Ha, also known with the Bantu language prefix as "Giha, Ikiha," or "Kiha," is a Bantu language spoken by the Ha people of the Kigoma Region of Tanzania, spoken on the eastern side of Lake Tanganyika up to the headwaters of the Mikonga.
 It is closely related to the languages of Rwanda and Burundi; neighboring dialects are reported to be mutually intelligible with Kirundi. Suba language
Suba, also known as Olusuba, is a Bantu language spoken by the Suba people of Kenya.
 The language features an extensive noun-classification system using prefixes that address gender and number.
 Suba clans are located on the eastern shore and islands of Lake Victoria in Kenya and Tanzania.
 They have formed alliances with neighboring clans, such as the Luo people, via intermarriages, and as a result a majority of Suba people are bilingual in Dholuo.
 The Suba religion has an ancient polytheistic history that includes writings of diverse, ancestral spirits.
 A recent revival of the Suba language and its culture has influenced the increasing number of native speakers each year.
