What are the last names of the people who influenced each other, according to Matthews?
Warrack emphasises that Holst acquired an instinctive understanding—perhaps more so than any English composer—of the importance of folksong. In it he found "a new concept not only of how melody might be organized, but of what the implications were for the development of a mature artistic language". Holst did not found or lead a school of composition; nevertheless, he exercised influences over both contemporaries and successors. According to Short, Vaughan Williams described Holst as "the greatest influence on my music", although Matthews asserts that each influenced the other equally. Among later composers, Michael Tippett is acknowledged by Short as Holst's "most significant artistic successor", both in terms of compositional style and because Tippett, who succeeded Holst as director of music at Morley College, maintained the spirit of Holst's music there. Of an early encounter with Holst, Tippett later wrote: "Holst seemed to look right inside me, with an acute spiritual vision". Kennedy observes that "a new generation of listeners ... recognized in Holst the fount of much that they admired in the music of Britten and Tippett". Holst's pupil Edmund Rubbra acknowledged how he and other younger English composers had adopted Holst's economy of style: "With what enthusiasm did we pare down our music to the very bone".Short cites other English composers who are in debt to Holst, in particular William Walton and Benjamin Britten, and suggests that Holst's influence may have been felt further afield. Above all, Short recognises Holst as a composer for the people, who believed it was a composer's duty to provide music for practical purposes—festivals, celebrations, ceremonies, Christmas carols or simple hymn tunes. Thus, says Short, "many people who may never have heard any of [Holst's] major works ... have nevertheless derived great pleasure from hearing or singing such small masterpieces as the carol 'In the Bleak Midwinter'".On 27 September 2009, after a weekend of concerts at Chichester Cathedral in memory of Holst, a new memorial was unveiled to mark the 75th anniversary of the composer's death. It is inscribed with words from the text of The Hymn of Jesus: "The heavenly spheres make music for us". In April 2011 a BBC television documentary, Holst: In the Bleak Midwinter, charted Holst's life with particular reference to his support for socialism and the cause of working people.
