Question: What composer strongly influenced both by the great composers of the Italian Baroque and by the middle-German polyphonic choral tradition, had a museum in Mayfair, London dedicated to his life and work?
Context: George Frideric (or Frederick) Handel ( ; born Georg Friedrich Händel ] ; 23 February 1685 (O.S.) [(N.S.) 5 March] – 14 April 1759) was a German, later British, baroque composer who spent the bulk of his career in London, becoming well known for his operas, oratorios, anthems, and organ concertos. Handel received important training in Halle and worked as a composer in Hamburg and Italy before settling in London in 1712; he became a naturalised British subject in 1727.  He was strongly influenced both by the great composers of the Italian Baroque and by the middle-German polyphonic choral tradition. Georgy Vasilyevich Sviridov (Russian: Гео́ргий Васи́льевич Свири́дов; his patronymic is also transliterated "Vasil'yevich", "Vasilievich", and "Vasil'evich") (December 16, 1915 – January 6, 1998) was a Russian neoromantic composer, active in the Soviet era.  He is most widely known for his choral music, strongly influenced by the traditional chant of the Russian Orthodox Church, as well as his orchestral works which often celebrate elements of Russian culture.  Sviridov employed, in his choral music especially, rich and dense harmonic textures, embracing a romantic-era tonality; his works would come to incorporate not only sacred elements of Russian church music, including vocal work for the basso profundo, but also display the influence of Eastern European folk music, 19th-century European romantic composers (especially Tchaikovsky), as well as neoromantic contemporaries outside of Russia.  He wrote musical settings of Russian Romantic-era poetry by poets such as Lermontov, Tyutchev and Blok.  Sviridov enjoyed critical acclaim for much of his career in the USSR. L'arte del violino is a noteworthy and influential musical composition by Italian Baroque violinist and composer Pietro Locatelli.  The twelve concerti were written for solo violin, strings, and basso continuo and were published in 1733 as the composer's third opus.  The virtuosic style and artistry present in the work strongly influenced violin playing in the 18th century and cemented Locatelli's reputation as a pioneer of modern violin technique. Festival Singers of Atlanta, which founded in 1981, is an ensemble which presents choral music of the Renaissance, Baroque, and Contemporary eras to audiences in Atlanta and the American Southeast.  The group particularly specializes in unaccompanied music of the Renaissance and 20th-21st century music that resonates with the Anglican choral tradition. Outside France the island of Corsica is perhaps best known musically for its polyphonic choral tradition.  The rebirth of this genre was linked with the rise of Corsican nationalism in the 1970s.  The anthem of Corsica is "Dio vi Salvi Regina". Antonio Lucio Vivaldi (] ; 4 March 1678 – 28 July 1741) was an Italian Baroque composer, virtuoso violinist, teacher and cleric.  Born in Venice, he is recognized as one of the greatest Baroque composers, and his influence during his lifetime was widespread across Europe.  He composed many instrumental concertos, for the violin and a variety of other instruments, as well as sacred choral works and more than forty operas. His best-known work is a series of violin concertos known as "The Four Seasons". Meane (sometimes spelled mean) is a vocal music term used by English composers of polyphonic choral music during the English pre-Reformation and Reformation eras.  At this time choral music written for the Church of England was often voiced in 5 parts, with MAATB (Meane, Alto, Alto, Tenor, Bass) or TrMATB (Treble, Meane, Alto, Tenor, Bass) being frequent voicings utilized by William Byrd, Thomas Tallis and their contemporaries.  The meane part was typically sung by boys whose voices were not as high as a treble or boy soprano but were not as low as a countertenor.  Occasionally the meane line would be sung by a combination of treble and countertenor voices.

The Handel House Museum is a museum in Mayfair, London dedicated to the life and works of the German-born British baroque composer George Frideric Handel, who made his home in London in 1712 and eventually became a British citizen in 1727.  Handel was the first occupant of 25 Brook Street, which he rented from 1723 until his death there in 1759.  Almost all his works after 1723, amongst them many of his best-known operas, oratorios and ceremonial music, were composed and partially rehearsed in the house, which contained a variety of keyboard instruments, including harpsichords, a clavichord and a small chamber organ. The Dublin Choral Foundation was established in 1996 to promote the development of choirs of excellence in Dublin and to provide a musical education for children hitherto only available in the cathedral choral tradition, Dublin Choral Foundation is now recognised as one of Ireland’s leading choral establishments.  The two choirs of Dublin Choral Foundation, The Lassus Scholars and Piccolo Lasso, directed by Ite O'Donovan, cater for singers of all ages.  They are named after the great composer and virtuoso of Renaissance polyphony Orlande de Lassus (1532–1594).
