 It is around 10 km north-west of Duns, in the Lammermuir Hills.
 The Dye Water runs through the village, flowing east towards its confluence with the Whiteadder Water nearby.
 The opera "Lucia di Lammermoor", written by Gaetano Donizetti and based on Sir Walter Scott's "The Bride of Lammermoor", was set in Longformacus.
Emilio Venturini (1878 - 1952) was an Italian operatic lyric tenor known for his portrayal of character roles.
 He made his professional opera debut in 1900 in Italy where he remained for the next several years.

 He made his La Scala debut in 1903 as Froh in Wagner's "Das Rheingold" and sang in the premiere of Umberto Giordano's "Siberia".
 In 1904, he originated the role of Prince Yamadori in Puccini's "Madama Butterfly" at La Scala.
 In 1905, Venturini joined the roster of the Opéra National de Paris.
 In 1907 he moved to London to sing with Royal Opera at Covent Garden.
 In 1910, Venturini became a member of the Chicago Opera Association where he performed roles until the summer of 1917.
 While in Chicago he sang mostly character parts but did sing some major roles like Turiddu in "Cavalleria rusticana", Edgardo in "Lucia di Lammermoor" and the Pinkerton in "Madama Butterfly".
 In 1911 he sang the roles of Cassio in Verdi's "Otello" and Spoletta in Puccini's "Tosca" at the Metropolitan Opera.

The Bride of Lammermoor is an historical novel by Sir Walter Scott, published in 1819.
 The novel is set in the Lammermuir Hills of south-east Scotland, and tells of a tragic love affair between young Lucy Ashton and her family's enemy Edgar Ravenswood.
 Scott indicated the plot was based on an actual incident.
 "The Bride of Lammermoor" and "A Legend of Montrose" were published together as the third of Scott's "Tales of My Landlord" series.
 As with all the Waverley Novels, "The Bride of Lammermuir" was published anonymously.
 The novel claims that the story was an oral tradition, collected by one "Peter Pattieson", and subsequently published by "Jedediah Cleishbotham".
 The 1830 "Waverley edition" includes an introduction by Scott, discussing his actual sources.
 The later edition also changes the date of the events: the first edition sets the story in the 17th century; the 1830 edition sets it in the reign of Queen Anne, after the 1707 Acts of Union which joined Scotland and England.
 The story is the basis for Donizetti's 1835 opera "Lucia di Lammermoor".
La dame blanche ("The White Lady") is an opéra comique in three acts by the French composer François-Adrien Boieldieu.
 The libretto was written by Eugène Scribe and is based on episodes from no fewer than five works of the Scottish writer Sir Walter Scott, including his novels "The Monastery", "Guy Mannering", and "The Abbot".
 The opera has typical elements of the Romantic in its Gothic mode, including an exotic Scottish locale, a lost heir, a mysterious castle, a hidden fortune, and a ghost, in this case benevolent.
 The work was one of the first attempts to introduce the fantastic into opera and is a model for works such as Giacomo Meyerbeer's "Robert le diable" and Charles Gounod's "Faust".
 The opera's musical style also heavily influenced later operas like "Lucia di Lammermoor", "I puritani" and "La jolie fille de Perth".
In 1841, while Donizetti was in Paris waiting for the libretto to be completed for a commission by La Scala, he had a chance encounter with Gustave Vaëz, who had co-written the libretti for two of his earlier operas, "Lucie de Lammermoor" (the French version of "Lucia di Lammermoor") and "La favorite".
 He asked Vaëz if he could provide a libretto for a short opera to keep him busy while waiting for the La Scala project to advance.
 Vaëz quickly created "Deux hommes et une femme" ("Two Men and a Woman"), a comic piece in one act consisting of eight musical numbers connected by spoken dialogue.
 According to Vaëz, Donizetti completed the score in eight days.
 However, the Opéra-Comique rejected it and Donizetti then had the libretto translated into Italian for an intended performance at the Teatro del Fondo in Naples.
 Following the death of the Teatro del Fondo's impresario, Domenico Barbaja, the Naples performance fell through.
 The score, still unperformed, was found in Donizetti's effects when he died in 1848.
Lucia di Lammermoor is a "dramma tragico" (tragic opera) in three acts by Gaetano Donizetti.
 Salvadore Cammarano wrote the Italian-language libretto loosely based upon Sir Walter Scott's historical novel "The Bride of Lammermoor".
Harolyn Blackwell (born November 23, 1955) is an American lyric coloratura soprano who has performed in many of the world's finest opera houses, concert halls, and theaters in operas, oratorios, recitals, and Broadway musicals.
 Initially known for her work within musical theater during the early 1980s, Blackwell moved into the field of opera and by 1987 had established herself as an artist within the soubrette repertoire in many major opera houses both in the United States and in Europe.
 Feeling that she was being "type cast" into one particular kind of role, Blackwell strove to establish herself within the lyric coloratura repertoire beginning in the mid-1990s.
 With the aid of such companies as Seattle Opera, Blackwell successfully made this move and is now an interpreter of such roles as Lucia in Donizetti's "Lucia di Lammermoor" and Olympia in Offenbach's "Les contes d'Hoffman".
 She has also periodically returned to musical theater performances throughout her career in staged productions, concert work, and recitals.
 Blackwell is known for her interpretations and recordings of the works of Leonard Bernstein.
Das Liebesverbot ("The Ban on Love", WWV 38), is an early opera in two acts by Richard Wagner, with the libretto written by the composer after Shakespeare's "Measure for Measure".
 Described as a "Große komische Oper ", it was composed in 1834, and Wagner conducted the premiere in 1836 at Magdeburg.
 Poorly attended and with a lead singer who forgot the words and had to improvise, it was a resounding flop and its second performance had to be cancelled after a fist-fight between the prima donna's husband and the lead tenor broke out backstage before the curtain had even risen; only three people were in the audience.
 It was never performed again in Wagner's lifetime.
