The "atenteben (atɛntɛbɛn)" is a bamboo flute from Ghana.
 It is played vertically, like the European recorder, and, like the recorder, can be played diatonically as well as chromatically.
 Although originally used as a traditional instrument (most often in funeral processions), beginning in the 20th century it has also been used in contemporary and classical music.
 Several players have attained high levels of virtuosity and are able to play Western as well as African music on the instrument.
William James Young (1800–1870), probably born in Philadelphia, was indentured as an apprentice to instrument maker Thomas Whitney of Philadelphia for seven years beginning in 1813.
 Young was first listed in the 1825 Philadelphia directory as a mathematical instrument maker.
 He continued in business by himself until 1867 when Thomas N. Watson and Charles S. Heller joined him and the firm became known as William J. Young & Co.
 Young's son Alfred later took over the company and it became known as Young & Sons.
 It produced surveying and other precision devices until Keuffel and Esser of New York City acquired the company in 1918.
 Even then, K&E continued to offer a separate line of instruments with the Young & Sons name so as to maintain the customer base that had been built over the years.
 K&E moved the Young operation to Hoboken, New Jersey, in 1922.
The standard viola is about as big as can conveniently be played under the chin.
 The physicist/instrument maker Carleen Hutchins, working during the 1960s, reasoned that a viola played vertically could be made larger, and that a larger viola might produce a better sound.
 Based on principles of instrument design she had observed in top-quality existing instruments, Hutchins designed a viola about longer than the regular viola, intended to be played vertically like a cello.
 (Despite Hutchins's original intention, a few violists have played her viola horizontally.)
The suroz is a bowed string instrument with a long neck, similar to a fiddle or sarangi and played vertically.
 It is considered the national instrument of the Baloch people of Iran, Afghanistan, and Pakistan.
Hugo Walter Voigtlander (November 8, 1859 – January 7, 1933) was a German-American musician who played violin, viola, and viola d'amore.
 He was also an instrument maker, and a collector and arranger of viola d'amore music.
 As a youth he studied at the Royal Conservatory of Music in Leipzig and played violin and viola in several professional orchestras in Germany.
 He emigrated to the United States in 1885 where he spent ten years playing viola and viola d'amore with various professional chamber groups in and around Detroit, Michigan.
 He then spent two years in Pittsburgh, Pennsylvania playing in the Pittsburgh Symphony Orchestra, and in 1897 moved to New York City, where he played in a number of professional orchestras.
 In addition to playing viola d'amore, Walter Voigtlander taught viola d'amore, and made and collected numerous arrangements for the instrument.
Carleen Maley Hutchins (May 24, 1911 – August 7, 2009) was an American former high school science teacher, violinmaker and researcher, best known for her creation, in the 1950s/60s, of a family of eight proportionally-sized violins now known as the violin octet (e.g., the vertical viola) and for a considerable body of research into the acoustics of violins.
 She was born in Springfield, Massachusetts.
Conch, or conque, also known as a "seashell horn" or "shell trumpet", is a musical instrument (often a signal instrument), a wind instrument that is made from a seashell (conch), the shell of several different kinds of very large sea snails.
 As described by instrument maker Bart Hopkins, such shells are a "gift from the sea that provides a natural conical bore is conch.
 Conch shell trumpets have been played in many Pacific Island countries, as well as South America and Southern Asia.
 They produce warm, full, and far-carrying tone."
Matt Nolan (born 1974) is an English drummer, bespoke musical instrument maker and metal sculptor.
 Nolan works as an independent cymbal and gong maker from his workshop in Bath in the South-West of England.
 Nolan is part of a small community of one-man "artisan cymbalsmiths" and attracts the interest of professional drummers and musicians.
 Nolan was an electrical engineer before he became an instrument maker.
The saw duang (Thai: ซอด้วง ,  ] , rtgs: "so duang" ) is a two-stringed instrument used in traditional Thai music.
 The sound is produced by the bow made from horsetail hair which goes between the strings made from silk.
 The bow has to be tilted to switch from one string to another.
 Saw duang is light and played vertically on the lap.
 It creates a bright tone unlike the Saw u which produces a mellow sound.
 Another instrument which is similar to the Saw duang is the Chinese stringed instrument called Huqin.

Question: Where was the instrument maker working in the 60s that reasoned that a viola played vertically could be made larger born?
Answer: Springfield, Massachusetts.
