A minor (abbreviated Am) is a minor scale based on A, consisting of the pitches A, B, C, D, E, F, and G. The harmonic minor scale raises the G to G♯. Its key signature has no flats or sharps (see below: Scales and keys).

Its relative major is C major, and its parallel major is A major.

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary.

Johann Joachim Quantz considered A minor, along with C minor, much more suitable for expressing "the sad affect" than other minor keys (Versuch einer Anweisung die Flöte traversiere zu spielen^{[Full citation needed]}).

Whereas traditionally key signatures were cancelled whenever the new key signature had fewer sharps or flats than the old key signature, in modern popular and commercial music, cancellation is only done when C major or A minor replaces another key.

Edvard Hagerup Grieg /ˈɛdʋɑɖ ˈhɑːgəɾʉːp gɾiːg/ (15 June 1843 – 4 September 1907) was a Norwegian composer and pianist. He is best known for his Piano Concerto in A minor, for his incidental music to Henrik Ibsen's play Peer Gynt (which includes Morning Mood and In the Hall of the Mountain King), and for his collection of piano miniatures Lyric Pieces.

Edvard Hagerup Grieg was born in Bergen, Norway on 15 June 1843. His parents were Alexander Grieg (1806–1875), a merchant and vice consul in Bergen, and Gesine Judithe Hagerup (1814–1875), a music teacher and daughter of Edvard Hagerup. The family name, originally spelled Greig, has Scottish origins. After the Battle of Culloden in 1746, Grieg's great-grandfather traveled widely, settling in Norway about 1770, and establishing business interests in Bergen.

Edvard Grieg was raised in a musical area. His mother was his first piano teacher and taught him to play at the age of 6. Grieg studied in several schools,^{[clarification needed]} including Tank's School. He often brought in samples of his music to class.^{[citation needed]}

Frédéric François Chopin ( /ˈʃoʊpæn/; French pronunciation: [fʁe.de.ʁik ʃɔ.pɛ̃]; Polish: Fryderyk Franciszek Chopin, also phonetically Szopen; 22 February or 1 March 1810 – 17 October 1849) was a Polish composer and virtuoso pianist of French-Polish parentage. He is considered one of the great masters of Romantic music. Chopin was born in Żelazowa Wola, a village in the Duchy of Warsaw. A renowned child-prodigy pianist and composer, Chopin grew up in Warsaw and completed his music education there; he composed many mature works in Warsaw before leaving Poland in 1830 at age 20, shortly before the November 1830 Uprising.

Following the Russian suppression of the Uprising, he settled in Paris as part of Poland's Great Emigration. During the remaining 19 years of his life, Chopin gave only some 30 public performances, preferring the more intimate atmosphere of the salon; he supported himself by sales of his compositions and as a piano teacher. After some romantic dalliances with Polish women, including an abortive engagement, from 1837 to 1847 he carried on a relationship with the French writer Amantine Dupin (pen name "George Sand"). For most of his life, Chopin suffered from poor health; he died in Paris in 1849 at age 39.
