Little (Chamber) Symphony No. 1 “Le Printemps” Op. 43, as the first of a collection of six “Little Symphonies,” by Darius Milhaud is a symphony by name, due to its length of just over 3 minutes.
 This piece should not be confused with Milhaud's Symphony No. 1.
 The piece was composed in Rio de Janeiro in the year 1917.
 It first premiered in Rio de Janeiro in 1918, and was published by Universal in 1922.
 The influence of Brazilian culture, jazz, and polytonality is very clearly seen in this series of symphonies.
 According to Milhaud himself, he was quite attracted to the unusual quality of small groups of instruments, which is why he embarked on his series of Petites Symphonies.
 Due to the fact that he was living in Brazil, acting as assistant to the diplomat/poet Paul Claudel, at the time he wrote this first symphony some of the Brazilian influence can be viewed in his work.
 This first symphony was written for piccolo, flute, clarinet, oboe, harp, 2 violins, viola, and cello.
 Overall, this piece has a very simple melody, contains polytonal elements, and possesses a pastoral, folkish feeling throughout.
 The melodies and pitches evoke a light, airy feeling, such as that of the spring, thus alluding to the symphony's subtitle.
The London symphonies, sometimes called the Salomon symphonies after Johann Peter Salomon who introduced London to Joseph Haydn, were composed by Joseph Haydn between 1791 and 1795.
 They can be categorized into two groups: Symphonies Nos. 93–98, which were composed during Haydn's first visit to London, and Symphonies Nos. 99–104, composed in Vienna and London for Haydn's second visit.
G minor has been considered the key through which Wolfgang Amadeus Mozart best expressed sadness and tragedy, and many of his minor key works are in G minor.
 Though Mozart touched on various minor keys in his symphonies, G minor is the only minor key he used as a main key for his numbered symphonies.
 In the Classical period, symphonies in G minor almost always used four horns, two in G and two in B♭ alto.
 Another convention of G minor symphonies observed in Mozart's No. 25 and No. 40 was the choice of the subdominant of the relative key (B♭ major), E♭ major, for the slow movement; other non-Mozart examples of this practice include J.C. Bach Opus 6 No. 6 from 1769, Haydn's No. 39 (1768/69) and Johann Baptist Wanhal's G minor symphony sometime before 1771 (Bryan Gm1).
The Symphony No. 80 in D minor, Hoboken 1/80, is a symphony composed by Joseph Haydn in 1784 as part of a trio of symphonies that also included symphonies 79 and 81.
 It is one of the relatively few later symphonies by Haydn to be in the minor mode.
 Symphony 80 is highly structured with both outer movements in sonata form.
 There is a common (though not strict) modulation pattern seen in all four movements.
Praisesong for the Widow is a 1983 novel by Paule Marshall that takes place in the mid-1970s, chronicling the life of Avey Johnson, a 64-year-old African-American widow on a physical and emotional journey in the Caribbean island of Carriacou.
 Throughout the novel, there are many flashbacks to Avey's earlier life experiences with her late husband, Jerome Johnson, as well as childhood events that reconnect her with her lost cultural roots.
While most symphonies have a "number", many symphonies are known by their "(nick)name".
Count Morzin was an aristocrat of the Austrian Empire during the 18th century.
 He is remembered today as the first person to employ the composer Joseph Haydn as his Kapellmeister, or music director.
 The first few of Haydn's many symphonies were written for the Count.
The War Symphonies: Shostakovich Against Stalin (sometimes titled Shostakovich Against Stalin: The War Symphonies) is a 1997 documentary film about Soviet composer Dmitri Shostakovich.
 It focuses on the period between 1936 and 1945, during which Shostakovich composed his Fourth, Fifth, Sixth, Seventh, Eighth, and Ninth Symphonies, but also briefly discusses other works in the composer's oeuvre, such as his "Lady Macbeth of the Mtsensk District.
Troubled Island is an American opera in three acts composed by William Grant Still, with a libretto begun by poet Langston Hughes and completed by Verna Arvey.
 She married the composer following their collaboration.
William Grant Still (May 11, 1895 – December 3, 1978) was an American composer, who composed more than 150 works, including five symphonies and eight operas.
