Ivor Novello (15 January 1893 – 6 March 1951), born David Ivor Davies, was a Welsh composer and actor who became one of the most popular British entertainers of the first half of the 20th century.
Careless Rapture is a 'musical play' by the Welsh composer Ivor Novello and lyrics by Christopher Hassall.
 It premiered on 11 September 1936 at the Theatre Royal, Drury Lane.
 It ran for 295 performances, a relatively modest success given Novello's other major successes.
David is a short film made in 1951 about the Welsh miner and poet David Rees Griffiths.
 It was directed by Paul Dickson, who also wrote the script, shot by Ronald Anscombe, produced by James Carr, and distributed by Regent Films.
 Leading Welsh composer Grace Williams wrote the score for the film.
 The film is 38 minutes long and was given a U certificate.
 It was the Welsh contribution to the Festival of Britain film festival.
John Thomas (1 March 1826 – 19 March 1913) was a Welsh composer and harpist.
 The bardic name Pencerdd Gwalia (Chief of the Welsh minstrels) was conferred on him at the 1861 Aberdare Eisteddfod.
Joseph Parry (21 May 1841 – 17 February 1903) was a Welsh composer and musician.
 Born in Merthyr Tydfil, Wales, he is best known as the composer of "Myfanwy" and the hymn tune "Aberystwyth", which the National anthem of South Africa, Nkosi Sikelel' iAfrika, is said to be based on.
 Parry was also the first Welshman to compose an opera; his composition, "Blodwen", was the first opera in the Welsh language.
Tornrak is the third opera by Welsh composer John Metcalf.
 It has an English-language libretto by Michael Wilcox with Inuktitut sections translated by Blendina Makkik.
 Set between the worlds of the Canadian Arctic and Victorian Britain, it features Inuit throat singing and other extended vocal techniques that give the Arctic scenes a distinct character.
 The opera was composed between 1986 and 1990 when Metcalf was working in Canada.
 It was first staged in 1990 in a co-production by the Banff Centre, where Metcalf worked, and the Welsh National Opera who had commissioned the work.
Betty Careless or Betsy Careless (c.1704–1739) was a notorious prostitute and later bagnio-owner in 18th-century London.
 Probably born Elizabeth Carless (though she later used the name Mrs. Elizabeth Biddulph too), she adapted her name to better suit her profession.
 Her name, beauty and reputation made her, like Sally Salisbury before her, something of an archetypal courtesan for the popular culture of the day.
Morfydd Llwyn Owen (1 October 1891 – 7 September 1918) was a Welsh composer, pianist and mezzo-soprano.
 Though she died shortly before her 27th birthday, Owen was a prolific composer, as well as a member of influential intellectual circles.
Mansel Treharne Thomas OBE (12 June 1909 – 8 January 1986) was a Welsh composer and conductor, who worked mainly in South Wales.
 He was one of the most influential musicians of his generation, known as a composer, conductor and adjudicator.
 He was for many years employed by the BBC and promoted the careers of many composers and performers.
 He himself wrote vocal, choral (mixed, female, children’s and male voices), instrumental (solo and chamber), band and orchestral music, specialising in setting songs and poetry.
 Many of his orchestral and chamber music pieces are based on Welsh folk songs and dances.
Guto Pryderi Puw (born 1971) is a Welsh composer, university lecturer and conductor.
 He is considered to be one of the most promising Welsh composers of his generation and a key figure in current Welsh music.
 Puw's music has been broadcast on BBC Radio 3 and been featured on television programmes for the BBC and S4C.
 He has twice been awarded the Composer's Medal at the National Eisteddfod.
