Mozart!

Wolfgang Amadeus Mozart was a prolific and influential composer of the Classical era. His more than 600 compositions include works widely acknowledged as pinnacles of symphonic, concertante, chamber, piano, operatic, and choral music, and he is among the most enduringly popular of classical composers.
Mozart was born in Salzburg into a musical family and showed indications of prodigious abilities at a very young age. When he was five years old, he could both read and write music and had precocious skills as a keyboard and violin player. Much of his childhood and adolescence was taken up with tours, which included performances before many of the royal courts of Europe. In 1773, aged 17, he accepted a post as a court musician in Salzburg, but was unhappy with his low pay and limited opportunities. Over the next eight years, he frequently traveled in search of a better position and composed abundantly. This situation continued until his dismissal from Salzburg in 1781 by his employer, the Prince-Archbishop, and his subsequent departure for Vienna.
He spent the rest of his busy life in Vienna, where he achieved relative fame. However, his finances remained precarious, with periods of prosperity and of penury. In 1782, he married Constanze Weber against the wishes of his family; six children were born, of whom two survived infancy. Musically, this was a period of outstanding creativity which saw the production of many of his best known symphonic, concertante and operatic works, and his final, incomplete Requiem. The circumstances of his death, at the age of 35, have been much mythologized, but were most likely commonplace.
In his youth, Mozart had used his gifts of imitation and mimicry to learn from the works of others. From these lessons, in maturity, he fashioned a style that ranged in mood from the light and pleasant to the dark and violent, from a vision of humanity "redeemed through art, forgiven, and reconciled with nature and the absolute". His influence on all subsequent classical music has been profound. Beethoven wrote much of his early music in Mozart's shadow. Joseph Haydn, sometime mentor and later friend and admirer, wrote, "Posterity will not see such a talent again in 100 years". Others claim that, more than two centuries after his death, his talent remains unsurpassed.

Chopsticks...

Frédéric Chopin (1 March 1810– 17 October 1849) was a Polish composer and virtuoso pianist of the Romantic period. He is widely regarded as the greatest Polish composer, and ranks as one of music's greatest tone poets.
Chopin was born in the village of Żelazowa Wola, in the Duchy of Warsaw, to a Polish mother and French-expatriate father, and in his early life was regarded as a child-prodigy pianist. In November 1830, at the age of 20, he went abroad; following the suppression of the Polish November Uprising of 1830–31, he became one of many expatriates of the Polish "Great Emigration."
In Paris, Chopin made a comfortable living as a composer and piano teacher, while giving few public performances. Though an ardent Polish patriot, in France he used the French versions of his names and eventually, to avoid having to rely on Imperial Russian documents, became a French citizen. After some ill-fated romantic involvements with Polish women, from 1837 to 1847 he had a turbulent relationship with the French writer George Sand (Aurore Dudevant). Always in frail health, in 1849 he died in Paris, at the age of 39, of chronic pulmonary tuberculosis.
Chopin's extant compositions were written primarily for the piano as a solo instrument. Though they are technically demanding, his style emphasizes nuance and expressive depth. Chopin invented musical forms such as the ballade and was responsible for major innovations in forms such as the piano sonata, waltz, nocturne, étude, impromptu and prelude. His works are mainstays of Romanticism in 19th-century classical music.

Hey there Franz!

Joseph Haydn was an Austrian composer. He was one of the most prominent composers of the classical period, and is called by some the "Father of the Symphony" and "Father of the String Quartet".
A life-long citizen of Austria, Haydn spent much of his career as a court musician for the wealthy Hungarian Esterházy family on their remote estate. Isolated from other composers and trends in music until the later part of his long life, he was, as he put it, "forced to become original".
During his lifetime, the composer was always known as Joseph Haydn. The form "Franz Joseph Haydn" is avoided by modern scholars and historians.
Joseph Haydn was the brother of Michael Haydn, himself a highly regarded composer, and Johann Evangelist Haydn, a tenor.

Georgy Frideric Handel

Handel was a German-born Baroque composer who is famous for his operas, oratorios and concerti grossi. Born as Georg Friedrich Händel in Halle, he spent most of his adult life in England, becoming a subject of the British crown on 22 January 1727. His most famous works are Messiah, an oratorio set to texts from the King James Bible; Water Music; and Music for the Royal Fireworks. Strongly influenced by the techniques of the great composers of the Italian Baroque and the English composer Henry Purcell, his music was known to many significant composers who came after him, including Haydn, Mozart, and Beethoven.

Ludwig van Beethoven

Ludwig van Beethoven was a German composer and pianist. He was a crucial figure in the transitional period between the Classical and Romantic eras in Western classical music, and remains one of the most respected and influential composers of all time.
Born in Bonn, then in the Electorate of Cologne (now in modern-day Germany), he moved to Vienna in his early twenties and settled there, studying with Joseph Haydn and quickly gaining a reputation as a virtuoso pianist. Beethoven's hearing gradually deteriorated beginning in his twenties, yet he continued to compose, and to conduct and perform, even after he was completely deaf.

Bach, Bach and more Bach!

Johann Sebastian Bach (31 March 1685 – 28 July 1750) was a German composer and organist whose sacred and secular works for choir, orchestra, and solo instruments drew together the strands of the Baroque period and brought it to its ultimate maturity. Although he introduced no new forms, he enriched the prevailing German style with a robust contrapuntal technique, an unrivalled control of harmonic and motif organization in composition for diverse musical forces, and the adaptation of rhythms and textures from abroad, particularly Italy and France.A few of Bach's most known pieces are his Brandenburg Concertos and his Concerto for Two Violins.
