A major (or the key of A) is a major scale based on A, with the pitches A, B, C♯, D, E, F♯, and G♯. Its key signature has three sharps.

In the treble, alto, and bass clefs, the G♯ in the key signature is placed higher than C♯. However, in the tenor clef, it would require a ledger line and so G♯ is placed lower than C♯.

Although not as rare in the symphonic literature as sharper keys, examples of symphonies in A major are not as numerous as for D major or G major. Beethoven's Symphony No. 7, Bruckner's Symphony No. 6 and Mendelssohn's Symphony No. 4 comprise a nearly complete list of symphonies in this key in the Romantic era. Mozart's Clarinet Concerto and Clarinet Quintet are both in A major, and generally Mozart was more likely to use clarinets in A major than in any other key besides E-flat major.

César-Auguste-Jean-Guillaume-Hubert Franck (10 December 1822 – 8 November 1890) was a composer, pianist, organist, and music teacher who worked in Paris during his adult life.

He was born at Liège, in what is now Belgium (though at the time of his birth it was under the Netherlands' control). In that city he gave his first concerts in 1834. He studied privately in Paris from 1835, where his teachers included Anton Reicha. After a brief return to Belgium, and a disastrous reception to an early oratorio Ruth, he moved to Paris, where he married and embarked on a career as teacher and organist. He gained a reputation as a formidable improviser, and travelled widely in France to demonstrate new instruments built by Aristide Cavaillé-Coll.

In 1858 he became organist at Sainte-Clotilde, a position he retained for the rest of his life. He became professor at the Paris Conservatoire in 1872; he took French nationality, a requirement of the appointment. His pupils included Vincent d'Indy, Ernest Chausson, Louis Vierne, Charles Tournemire, Guillaume Lekeu, and Henri Duparc. After acquiring the professorship Franck wrote several pieces that have entered the standard classical repertoire, including symphonic, chamber, and keyboard works.

Lars von Trier (Danish pronunciation: [ˈlɑːs fʌn ˈtʁiːˀɐ]; born Lars Trier; 30 April 1956) is a Danish film director and screenwriter. He is closely associated with the Dogme 95 collective – an avant-garde filmmaking movement – although his own films have taken a variety of approaches. His work has frequently divided the critics.

Von Trier began making films at the age of eleven. Raised by a communist mother and a socialist father in an austere environment, he converted at the age of 30 to the Catholic Church. Von Trier suffers periodically from depression, as well as various fears and phobias, including an intense fear of flying. As he himself said in an interview, "Basically, I'm afraid of everything in life, except filmmaking".. His first publicly released film was an experimental short called The Orchid Gardener (1977) and his first feature film came seven years later with The Element of Crime (1984). Among many other prizes, awards and nominations, he is the recipient of the Palme d'Or, the Grand Prix, and the Prix du Jury at the Cannes Film Festival.

Alfred Brendel KBE (born 5 January 1931) is an Austrian pianist, born in Czechoslovakia and a resident of the United Kingdom. He is also a poet and author.

Brendel was born in Wiesenberg, Czechoslovakia, now Loučná nad Desnou, Czech Republic, to a non-musical family. They moved to Zagreb when Brendel was six, and later to Graz, where they lived during World War II, towards the end of which the 14-year old Brendel was sent to Yugoslavia to dig trenches. However, he developed frostbite and was taken to hospital. Brendel began piano lessons when he was six with Sofija Deželić, and at 14 he studied piano with Ludovica von Kaan and composition in the Graz Conservatory for the next two years, but otherwise had little formal music education.

After the war, Brendel composed music, as well as continuing to play the piano and to paint. However, he never had more formal piano lessons and although he attended masterclasses with Edwin Fischer and Eduard Steuermann, he was largely self-taught.
