Q: Context_1 : Charles Edward Ives ( ; October 20, 1874May 19, 1954) was an American modernist composer. He is one of the first American composers of international renown, though his music was largely ignored during his life, and many of his works went unperformed for many years. Over time, he came to be regarded as an "American original". He combined the American popular and church-music traditions of his youth with European art music, and was among the first composers to engage in a systematic program of experimental music, with musical techniques including polytonality, polyrhythm, tone clusters, aleatory elements, and quarter tones, foreshadowing many musical innovations of the 20th century. Context_2 : Daniel Evan Freeman (born 27 April 1959) is an American musicologist who specializes in European art music of the eighteenth century, in particular the musical culture of eighteenth-century Prague and the Bohemian lands. He is also active as a pianist and music editor. Context_3 : Art music (also known as Western classical music, cultivated music, serious music, canonic music, and more flippantly, real music or normal music) is an umbrella term that refers to musical traditions, implying advanced structural and theoretical considerations and a written musical tradition. "Serious" or "cultivated" music are terms frequently used as a contrast for ordinary, everyday music (popular and folk music, also called "vernacular music"). After the 20th century, art music was divided into two extensions: "serious music" and "light music". Context_4 : In the history of European art music, the term "common practice period" refers to the era between the formation and the dissolution of the tonal system. Though there are no exact dates for this phenomenon, most features of the common-practice period persisted from the mid to late baroque period, through the Classical and Romantic periods, or roughly from around 1650 to 1900. While certain prevailing patterns and conventions characterize the music of this period, the time period also saw considerable stylistic evolution. Some conventions evolved during this period that were rarely employed at other times during what may still be labeled "common practice" (for example, Sonata Form). Thus, the dates 16501900 are necessarily nebulous and arbitrary borders that depend on context. The most important unifying feature through this time period concerns a harmonic language to which modern music theorists can apply Roman numeral analysis. Context_5 : The Festival Oude Muziek Utrecht ("Utrecht Early Music Festival") is an annual music festival that showcases and celebrates early European art music. The ten-day festival takes place in the Dutch city of Utrecht, and begins in August. The programme comprises concerts, activities, lectures, exhibitions, and a symposium. Context_6 : Assaf Shelleg (Hebrew: ), is a musicologist and pianist, a senior lecturer of musicology at The Hebrew University of Jerusalem. He was previously the Schusterman Visiting Assistant Professor of Musicology and Jewish Studies in the Department of Religious Studies at the University of Virginia (201114), and had taught prior to that as the visiting Efroymson Scholar in the Jewish, Islamic & Near Eastern Languages and Cultures Department at Washington University in St. Louis (200911). Shelleg specializes in twentieth-century Jewish and Israeli art music and has published in some of the leading journals in both musicology and Israel Studies on topics ranging from the historiography of modern Jewish art music to the theological networks of Israeli art music. Shelleg's book, "Jewish Contiguities and the Soundtrack of Israeli History", appeared in November 2014 with Oxford University Press. The book studies the emergence of modern Jewish art music in central and Western Europe (1910s-1930s) and its translocation to Palestine/Israel (1930s-1970s), exposing the legacies of European antisemitism and religious Judaism in the making of Israeli art music. Moving to consider the dislocation of modern Jewish art music the book examines the paradoxes embedded in a Zionist national culture whose rhetoric negated its pasts, only to mask process of hybridizations enchained by older legacies. "Jewish Contiguities" has won the 2015 Engle Prize for the study of Hebrew Music, and the 2016 Jordan Schnitzer Book Award. Context_7 : Vocal harmony is a style of vocal music in which a consonant note or notes are simultaneously sung as a main melody in a predominantly homophonic texture. Vocal harmonies are used in many subgenres of European art music, including Classical choral music and opera and in the popular styles from many Western cultures ranging from folk songs and musical theater pieces to rock ballads. In the simplest style of vocal harmony, the main vocal melody is supported by a single backup vocal line, either at a pitch which is above or below the main vocal line, often in thirds or sixths which fit in with the chord progression used in the song. In more complex vocal harmony arrangements, different backup singers may sing two or even three other notes at the same time as each of the main melody notes, mostly with consonant, pleasing-sounding thirds, sixths, and fifths (although dissonant notes may be used as short passing notes). Context_8 : David Wallis Reeves (February 14, 1838 March 8, 1900), also known as D. W. Reeves or Wally Reeves, was an American composer, cornetist, and bandleader. He developed the American march style, later made famous by the likes of John Philip Sousa, and his innovations include adding a countermelody to the American march form in 1876. Sousa called Reeves "The Father of Band Music in America", and stated he wished he himself had written Reeves' "Second Regiment Connecticut National Guard March". Charles Ives also borrowed from the "Second Connecticut" on four occasions. Context_9 : "Indian classical music is one of many forms of art music that have their roots in particular regional cultures. For other "classical" and art music traditions, see List of classical and art music traditions." Context_10 : Progressive music is music that subverts genre and expands stylistic boundaries outwards. Rooted in the idea of a cultural alternative, musical progressiveness embodies a continuous move between explicit and implicit references to genres and strategies derived from various cultural domains, such as European art music, Celtic folk, West Indian, or African. The word "progressive" comes from the basic concept of "progress", which refers to development and growth by accumulation, and is often deployed in numerous music genres such as progressive country, progressive folk, progressive jazz, and (most significantly) progressive rock. fact_1 : Charles Ives also borrowed from the "Second Connecticut" on four occasions. fact_2 : Charles Edward Ives ( ; October 20, 1874May 19, 1954) was an American modernist composer. fact_3 : He combined the American popular and church-music traditions of his youth with European art music, and was among the first composers to engage in a systematic program of experimental music, with musical techniques including polytonality, polyrhythm, tone clusters, aleatory elements, and quarter tones, foreshadowing many musical innovations of the 20th century. Answer: 1874May
A: What is the birthyear of the American composer that borrowed from "Second Connecticut" on four occasions and combined American popular and church-music traditions with European art music?
Rationale: From the fact_1 from context _8, and fact _2 and fact _3 from context _1, we can arrive at 1874 May which is accurate answer of generated question.
Q: Context_1 : Xcel Energy Inc. is a utility holding company based in Minneapolis, Minnesota, serving more than 3.3 million electric customers and 1.8 million natural gas customers in Minnesota, Michigan, Wisconsin, North Dakota, South Dakota, Colorado, Texas and New Mexico. It consists of four operating subsidiaries: Northern States Power-Minnesota, Northern States Power-Wisconsin, Public Service Company of Colorado, and Southwestern Public Service Co. Context_2 : The North American Light and Power Company was a utility holding company formed in South Bend, Indiana and run since 1916 by its President, Clement Studebaker, Jr., of the family famous for the Studebaker automobiles. The utility company remained a major subsidiary of the North American Company, until that conglomerate's 1940s breakup by the U.S. Securities and Exchange Commission (SEC). Context_3 : North American Co. v. Securities and Exchange Commission, 327 U.S. 686 (1946), is a United States Supreme Court case holding that a Securities and Exchange Commission (SEC) order under the Public Utility Holding Company Act (PUHCA) directing a public utility holding company to divest its securities of all companies except for one electric company did not violate the Commerce Clause or the Fifth Amendment to the United States Constitution. Context_4 : TECO Energy Inc. is an energy-related holding company based in Tampa, Florida, providing electricity to the greater Tampa area and central Florida, and natural gas throughout the state of Florida through its subsidiaries Tampa Electric Company and Peoples Gas Company respectively. Another subsidiary, TECO Services, Inc., provides IT, HR, legal, facilities, and other common services to Tampa Electric, Peoples Gas, and former TECO subsidiary New Mexico Gas Company. On September 4, 2015, Emera, a utility holding company based in Halifax, Nova Scotia, Canada, announced the pending acquisition of TECO Energy. That purchase closed on July 1, 2016, and TECO Energy, Inc. is now a wholly owned subsidiary of Emera, Inc. Context_5 : Spire Inc. () is a public utility holding company based in St. Louis, Missouri, providing natural gas service through its regulated core utility operations while engaging in non-regulated activities that provide business opportunities. Its primary subsidiary Laclede Gas Company is the largest natural gas distribution utility in Missouri, serving approximately 631,000 residential, commercial and industrial customers in the City of St. Louis and ten counties in eastern Missouri. Its corporate headquarters is located in the 700 Market building in downtown St. Louis. Context_6 : Nuclear Management Company was a contract/operations firm that operated six nuclear power plants in the midwest US. NMC provided operational collaborations between plants. NMC did not own the plants, nor the energy produced from them. NMC's corporate headquarters were in Hudson, Wisconsin. As of September 2008 the operating licenses for the last two plants overseen by NMC, Monticello and Prairie Island, were transferred to Northern States Power Company (a wholly owned subsidiary of Xcel Energy), the owner of the plants. All personnel and assets of NMC were transferred to NSP, rendering NMC defunct. Context_7 : The Ashland/Northern States Power Lakefront Superfund site is a contaminated region of the Wisconsin shoreline of Lake Superior that is being studied for remediation by Northern States Power Wisconsin (NSPW), as well as the Environmental Protection Agency (EPA), the Wisconsin Department of Natural Resources (WDNR). This site has held a manufactured gas plant from 1845 to 1947, as well as lumber manufacturing and treatment mills for four decades at the start of the 20th century, railcar loading facilities, and a municipal landfill. Additionally, a wastewater treatment plant is located on the premises, but is not in operation. Contamination of the site is currently believed to have been caused by all the parties mentioned above, or former owners of the property whose companies are no longer in business. The area is listed as a Superfund site by the EPA under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Releases of hazardous substances occurred onshore and migrated into sediment in Chequamagon Bay on Lake Superior. Context_8 : Northern States Power Company (NYSE: NSP ) was a publicly traded S&P 500 electric and natural gas utility holding company based in Minneapolis, Minnesota that is now a subsidiary of Xcel Energy (). Context_9 : Southern Company is an American gas and electric utility holding company based in the southern United States. It is headquartered in Atlanta, Georgia, with executive offices also located in Birmingham, Alabama. The company is currently the second largest utility company in the U.S., in terms of customer base. Through its subsidiaries it serves 9 million gas and electric utility customers in nine states. Southern Company's regulated regional electric utilities serve a 120000 sqmi territory with 27000 mi of distribution lines. Context_10 : The Pathfinder Atomic Power Plant was a nuclear power plant built by Northern States Power Company. It was located just northeast of Sioux Falls, South Dakota, and west of its suburb of Brandon. It was named for the 19th century explorer John C. "Pathfinder" Fremont and was constructed in the mid-1960s in partnership with a group of other investor-owned utilities. The main goal of this facility was to be a 'proof of concept' plant to gain practical experience in operating a nuclear plant. Some of the other participating utilities would also go on to build their own plants. Although the superheater developed by Allis-Chalmers was plagued with technical difficulties and which led to NSP's eventual decision to retire the reactor by 1967 (and convert the plant to run on gas and oil by 1968), the lessons NSP learned from Pathfinder served the company in its operation of the Prairie Island and Monticello nuclear plants. The longest Pathfinder ever ran at its full rated power was 30 minutes, and it was only then the company found the flaws that led to the decision to retire the reactor. After sitting idle for 23 years, the reactor vessel was removed from the plant in 1990 and transported to a low-level radioactive material dump in Washington. fact_1 : Northern States Power Company (NYSE: NSP ) was a publicly traded S&P 500 electric and natural gas utility holding company based in Minneapolis, Minnesota that is now a subsidiary of Xcel Energy (). fact_2 : Xcel Energy Inc. is a utility holding company based in Minneapolis, Minnesota, serving more than 3.3 million electric customers and 1.8 million natural gas customers in Minnesota, Michigan, Wisconsin, North Dakota, South Dakota, Colorado, Texas and New Mexico.
