A nation may refer to a community of people who share a common language, culture, ethnicity, descent, or history. In this definition, a nation has no physical borders. However, it can also refer to people who share a common territory and government (for example the inhabitants of a sovereign state) irrespective of their ethnic make-up. In international relations, nation can refer to a country or sovereign state. The word nation can more specifically refer to people of North American Indians, such as the Cherokee Nation that prefer this term over the contested term tribe.

According to Joseph Stalin writing in 1913 in Marxism and the National Question: "a nation is not a racial or tribal, but a historically constituted community of people;" "a nation is not a casual or ephemeral conglomeration, but a stable community of people;" "a common language is one of the characteristic features of a nation;" "a nation is formed only as a result of lengthy and systematic intercourse, as a result of people living together generation after generation;" "a common territory is one of the characteristic features of a nation;" "a common economic life, economic cohesion, is one of the characteristic features of a nation;" "a common psychological make-up, which manifests itself in a common culture, is one of the characteristic features of a nation;" "A nation is a historically constituted, stable community of people, formed on the basis of a common language, territory, economic life, and psychological make-up manifested in a common culture." According to Stalin, this would exclude Jews as they have no common territory.

William Thomas "Tommy" Emmanuel AM (born 31 May 1955) is an Australian guitarist and occasional singer, best known for his complex fingerstyle technique, energetic performances and the use of percussive effects on the guitar. In the May 2008 and 2010 issues of Guitar Player Magazine, he was named as "Best Acoustic Guitarist" in their readers' poll. In June 2010 Emmanuel was appointed a Member of the Order of Australia (AM).

Emmanuel was born in Australia in 1955. He received his first guitar in 1959 at age four, being taught by his mother to accompany her playing lap steel guitar. At the age of 7 he heard Chet Atkins on the radio. He vividly remembers this moment and says it greatly inspired him.

By the age of 6, in 1961, he was a working professional musician. Recognizing the musical talents of Tommy and his brother Phil, their father created a family band, sold the family home and took his family on the road. With the family living in two station wagons, much of Emmanuel’s childhood was spent touring Australia with his family, playing rhythm guitar, and rarely going to school. The family found it difficult living on the road; they were poor but never hungry, never settling in one place. His father would often drive ahead, organize interviews, advertising and finding the local music shop where they'd have an impromptu concert the next day. Eventually the New South Wales Department of Education insisted that the Emmanuel children needed to go to school regularly.

Jake Shimabukuro (born November 3, 1976 in Honolulu, Hawaiʻi) is a ukulele virtuoso known for his complex finger work. His music combines elements of jazz and rock.

Shimabukuro's mother gave him an ukulele at age four and he quickly took an interest in the instrument. A fifth generation Japanese-American, Shimabukuro initially gained attention in Hawaii in 1998 as a member of Pure Heart, a trio with Lopaka Colon (percussion), and Jon Yamasato (guitar). Shimabukuro was working at a music store in Honolulu when the group released its eponymous first album, featuring a sound and style somewhat similar to the Kaʻau Crater Boys. Their first album won them four Na Hoku Hanohano Awards (the Hawaiian counterpart of the Grammy Awards): Island Contemporary Album of the Year, Most Promising Artist(s), Album of the Year and Favorite Entertainment of the Year, the latter determined by unrestricted public vote. Jake also gained attention on his YouTube page, gaining several subscribers with videos of him playing popular songs on his ukelele.
