Question: Helge Lindberg was inspired by George Frideric Handel, and both worked in this style?
Context: The Handel Choir of Baltimore is a choir and oratorio society based in Baltimore, Maryland, which has been performing since the 1930s.  The ensemble is known for its annual performances of George Frideric Handel's "Messiah", an unbroken tradition since 1935.  During the tenure of Melinda O'Neal, Artistic Director and Conductor from 2004 to 2013, the Choir inaugurated the Handel Period Instrument Orchestra, an historically informed performance group.  In 2007, the Handel Choir of Baltimore and the Handel Society of Dartmouth College commissioned a work by Jonathan Leshnoff which came to be known as "Requiem for the Fallen".  In February 2008, Handel Choir joined with the Baltimore Chamber Orchestra to present the premiere performance of the Requiem. Terpsicore (HWV)(8b) is a prologue in the form of an opéra-ballet by George Frideric Handel.  Handel composed it in 1734 for a revision of his opera "Il pastor fido" which had first been presented in 1712.  The revision of "Il pastor fido" with "Terpsicore" as the prologue was first performed on 9 November 1734 at Covent Garden theatre in London, opening Handel's first season in that newly built theatre.  "Terpsicore" mixes dance along with solo and choral singing and was patterned after models in French operas, a particular source being "Les festes grecques et romaines" by Louis Fuzelier and Colin de Blamont, first presented in Paris in 1723.  The work featured the celebrated French dancer Marie Sallé as well as stars of Handel's Italian operas and was a success with audiences of the day. It is impossible to say how many flute sonatas were composed by George Frideric Handel, but the correct number is somewhere between none and eight.  There are many reasons for the confusion: some of the sonatas were originally written for other instruments, some have uncertain authenticity, some contain borrowings from other Handel works, and some were published (in an altered form) without Handel's knowledge.  At least six of the sonatas are known to contain music written by Handel, although he may not have intended some of them to have been played by the flute. The Hallische Händel-Ausgabe ("Halle Handel Edition") is a multi-volume collection of the works of George Frideric Handel.  It was first published in the 1950s: initially as an adjunct to the HG edition, but by 1958 as a collected edition in its own right.  The collection's abbreviation of "HHA" can be used to identify individual works by Handel, for example Handel's "Messiah" can be referred to as "HHA i/17" (with the Roman numeral "i" designating "series 1").  For practical use, the HHA numbering of Handel's works has been superseded by the HWV numbering system. Germanico is a serenata in one act, to a libretto of unknown authorship, which is ascribed to George Frideric Handel on the sole source, a copyist's manuscript in the library of the Conservatorio Luigi Cherubini in Florence.  The ascription to Handel, "del sig.  Hendl", is in the same hand that copied the music, suggesting it was contemporary with the writing of the score.  It was discovered in 2007 by the conductor and scholar and has been recorded by Deutsche Harmonia Mundi (EAN 886978604521).  The work appears to be authentic and to date from the earliest phase of Handel's sojourn in Italy, probably around 1708, leading to claims that it was Handel's first Italian opera. Helge Igor Lindberg (1887–1928) was a Finnish opera singer who was a popular concert singer in the 1920s throughout Europe.  He was also a sculptor.  Helge Lindberg first studied violin at the conservatory in Helsinki.  In 1907, he studied voice in Munich and finished his studies in Florence.  He was known for singing works by Johann Sebastian Bach, George Frideric Handel and Yrjö Kilpinen. 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. The Handel Music Prize, in German Händel-Preis, is an annual award, instituted in 1956, which is presented by the city of Halle, in Germany, in honour of the celebrated Baroque composer George Frideric Handel.  It is awarded, "for exceptional artistic, academic or politico-cultural services as far as these are connected with the city of Halle's Handel commemoration".  The prize consists of a diploma, a gold and enamel badge, and 10,000 euros in prize money and is presented during the annual Handel Festival, Halle. Between 1858 and 1902, the Händel-Gesellschaft ("German Handel Society") produced a collected 105-volume edition of the works of George Frideric Handel.  Even though the collection was initiated by the society, many of the volumes were published by Friedrich Chrysander working alone (Chrysander was the major contributor for almost all of the volumes).  The wording on the title page of the volumes is ""Georg Friedrich Händel's Werke.  Ausgabe der Deutschen Händelgesellschaft"" which translates as "Georg Friedrich Handel's works.  Edition of the German Handel Society".  Chrysander's work has been criticised, however the scale of his achievement is also praised.  The collection's abbreviation of "HG" can be used to identify individual works by Handel; for example Handel's "Messiah" can be referred to as "HG xlv" (with the Roman numerals "xlv" indicating that the work is in volume 45).  For practical use, the HG system has been superseded by the HWV numbering system.  The 105 volumes do not contain the complete works of Handel—with at least 250 of his works unpublished in the collection. The Handel organ concertos Op 7, HWV 306–311, refer to the six organ concertos for organ and orchestra composed by George Frideric Handel in London between 1740 and 1751, published posthumously in 1761 by the printing company of John Walsh.  They were written for performance during Handel's oratorios, contain almost entirely original material, including some of his most popular and inspired movements.
