Youth is the time of life between childhood and adulthood (maturity). Definitions of the specific age range that constitutes youth vary. An individual's actual maturity may not correspond to their chronological age, as immature individuals could exist at all ages.

Around the world, the terms "youth", "adolescent", "teenager", "kid", and "young person" are interchanged, often meaning the same thing, occasionally differentiated. Youth generally refers to a time of life that is neither childhood nor adulthood, but rather somewhere in-between. Youth also identifies a particular mindset of attitude, as in "He is very youthful". The term youth is also related to being young.

Youth is an alternative word to the scientifically-oriented adolescent and the common terms of teen and teenager. Another common title for youth is young person or young people.

August 12th was declared International Youth Day by The United Nations.

The age in which a person is considered a "youth", and thus eligible for special treatment under the law and throughout society varies around the world.

A person is a being, such as a human, that has certain capacities or attributes constituting personhood, the precise definition of which is the subject of much controversy.^{[vague language]} The common plural of "person", "people", is often used to refer to an entire nation or ethnic group (as in "a people"), so the plural "persons" is often used in contexts which require precision such as philosophical and legal writing.

In ancient Rome, the word "persona" (Latin) or "prosopon" (πρόσωπον: Greek) originally referred to the masks worn by actors on stage. The various masks represented the various "personae" in the stage play, while the masks themselves helped the actor's voice resonate and made it easier for the audience to hear.

In Roman law, the word "persona" became used to refer to a role played in court, and it became established that it was the role rather than the actor that could have rights, powers, and duties, because different individuals could assume the same roles, the rights, powers, and duties followed the role rather than the actor, and each individual could act in more than one role, each a different "person" in law.^{[tortured english][citation needed]}

Edward Benjamin Britten, Baron Britten,OM CH (22 November 1913 – 4 December 1976) was an English composer, conductor, and pianist; and one of the central figures of 20th century British classical music. He showed talent from an early age, and first came to public attention with the a cappella choral work A Boy Was Born in 1934. With the premiere of his opera Peter Grimes in 1945, he leapt to international fame. For the next fifteen years he devoted much of his compositional attention to writing operas, establishing him as one of the leading 20th century figures in this genre.

Britten's interests as a composer were wide-ranging; he produced important music in such varied genres as orchestral, choral, solo vocal (much of it written for his life partner, tenor Peter Pears), chamber and instrumental, as well as film music. He also took a great interest in writing music for children and amateur performers, and was an outstanding pianist and conductor.

Britten was born in Lowestoft, Suffolk, on 22 November 1913, the youngest of four children. His father, Robert, was a dentist, and his mother Edith, a talented amateur musician who gave Britten his first lessons in piano and notation. He showed musical gifts very early in life, making his first attempts at composition aged five, and thereafter composing prolifically as a child. He started piano lessons with a teacher from his pre-prep school when aged 7, and viola lessons with Audrey Alston when 10 years old.
