Joseph Humfrey Anger (3 June 186211 June 1913) was a Canadian organist, pianist, conductor, composer, and music educator of English birth.
 His compositional output consists mainly of church music and works for solo piano and organ.
 Some of his more well known works are "A Concert Overture" for organ (1895), the patriotic song "Hail Canada" (1911), and "Tintamarre, Morceau de Salon" (1911), all of which were published by Whaley, Royce & Co. The latter piece was notably the first published classical composition to thoroughly integrate true tone clusters.
 He also wrote the textbooks "Form in Music" and "A Treatise on Harmony", both of which were widely used in music schools in North America.
An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator.
 In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period (the run-up period).
 Then a known reference voltage of opposite polarity is applied to the integrator and is allowed to ramp until the integrator output returns to zero (the run-down period).
 The input voltage is computed as a function of the reference voltage, the constant run-up time period, and the measured run-down time period.
 The run-down time measurement is usually made in units of the converter's clock, so longer integration times allow for higher resolutions.
 Likewise, the speed of the converter can be improved by sacrificing resolution.
Sergei Vasilievich Rachmaninoff (Russian: Серге́й Васи́льевич Рахма́нинов , "Sergey Vasilyevich Rakhmaninov"; ] ; 1 April [O.S. 20 March] 1873 28 March 1943) was a Russian virtuoso pianist, composer, and conductor of the late-Romantic period, some of whose works are among the most popular in the romantic repertoire.
Pierre Jean Hyacinthe Adonis (or Antoine) Galoppe d'Onquaire (April 16, 1805 (Montdidier) – 9 January 1867 (Le Vésinet)) was a French writer and playwright.
 Among his operetta librettos, Jean-Baptiste Weckerlin's setting of "La Laitière de Trianon", "opéra de salon en 1 acte" is the best remembered, along with one song "Ça fait peur aux oiseaux" from the operetta "Bredouille", set to music by Paul Bernard (composer).
Morceaux de salon (French for "Salon Pieces"; Russian: Салонные Пьесы , "Salonnyye Pyesy"), Op.
 10, is a set of solo piano pieces composed by Russian composer Sergei Rachmaninoff in 1894.
His "morceaux de reception" for the Académie royale de peinture et de sculpture in 1672 were his portraits of the author Charles Perrault and of the financier Gédéon Berbier du Metz, president of the "Chambre des Comptes".
Morceaux de fantaisie (French for "Fantasy Pieces"; Russian: Пьесы Фантазии , "Pyesy Fantazii"), Op.
 3, is a set of five piano solo pieces composed by Sergei Rachmaninoff in 1892.
 The title reflects the pieces' imagery rather than their musical form, as none are actual fantasies.
 The set was dedicated to Anton Arensky, his harmony teacher at the Conservatory.
Prelude in C-sharp minor (Russian: Прелюдия ), Op.
 3, No. 2, is one of Sergei Rachmaninoff's most famous compositions.
 It is a ternary (ABA) prelude for piano in C-sharp minor, 62 bars long, and part of a set of five pieces entitled "Morceaux de fantaisie"; and also known as "The Bells of Moscow" since the introduction seems to reproduce the Kremlin's most solemn carillon chimes.
Étude de perfectionnement de la methode des methodes are two pieces by the Hungarian composer Franz Liszt, composed in 1842 and 1852.
 The first piece is called "Morceau de salon", S.142, followed by a revision, "Ab Irato", S.143, both composed in E minor.
 They are regarded as eccentric pieces with beautiful interludes of arpeggiated figures, though both are rarely performed.
Méringue (] ; Haitian Creole: "mereng" ), also called méringue lente or méringue de salon ("slow" or "salon" méringue), is a dance music and national symbol in Haiti.
 It is a string-based style played on the lute, guitar, and other string instruments unlike the primarily accordion-based "merengue", and is generally sung in Haitian Creole and French, as well as in English and Spanish.
