Here are three composers that changed the face of music for all time!!!

Johann Sebastian Bach (31 March 1685- 28 July 1750) (often referred to simply as Bach) was a German composer, organist, violist, and violinist whose ecclesiastical 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 did not introduce new forms, he enriched the prevailing German style with a robust contrapuntal technique, an unrivalled control of harmonic and motivic organisation, and the adaptation of rhythms, forms and textures from abroad, particularly from Italy and France.

Revered for their intellectual depth, technical command and artistic beauty, Bach's works include the Brandenburg concertos, the Goldberg Variations, the Partitas, The Well-Tempered Clavier, the Mass in B Minor, the St Matthew Passion, the St John Passion, the Magnificat, The Musical Offering, The Art of Fugue, the English and French Suites, the Sonatas and Partitas for solo violin, the Cello Suites, more than 200 surviving cantatas, and a similar number of organ works, including the celebrated Toccata and Fugue in D minor and Passacaglia and Fugue in C minor.

Bach's abilities as an organist were highly respected throughout Europe during his lifetime, although he was not widely recognised as a great composer until a revival of interest and performances of his music in the first half of the 19th century. He is now regarded as the supreme composer of the Baroque, and as one of the greatest of all time.

George Frideric Handel (German: Georg Friedrich Händel;  (23 February 1685 – 14 April 1759) was a German-English Baroque composer who is famous for his operas, oratorios, and concertos. Handel was born in Germany in the same year as JS Bach. He received critical musical training in Italy before settling in London and becoming a naturalised British subject. His works include Messiah, Water Music, and Music for the Royal Fireworks. He was strongly influenced by the techniques of the great composers of the Italian Baroque and the English composer Henry Purcell. 

Wolfgang Amadeus Mozart full baptismal name Johannes Chrysostomus Wolfgangus Theophilus Mozart(27 January 1756 – 5 December 1791), was a prolific and influential composer of the Classical era. He composed over 600 works, many acknowledged as pinnacles of symphonic, concertante, chamber, piano, operatic, and choral music. He is among the most enduringly popular of classical composers.

Mozart showed prodigious ability from his earliest childhood in Salzburg. Already competent on keyboard and violin, he composed from the age of five and performed before European royalty; at 17 he was engaged as a court musician in Salzburg, but grew restless and traveled in search of a better position, always composing abundantly. While visiting Vienna in 1781, he was dismissed from his Salzburg position. He chose to stay in the capital, where he achieved fame but little financial security. During his final years in Vienna, he composed many of his best-known symphonies, concertos, and operas, and the Requiem. The circumstances of his early death have been much mythologized. He was survived by his wife Constanze and two sons.

Mozart learned voraciously from others, and developed a brilliance and maturity of style that encompassed the light and graceful along with the dark and passionate—the whole informed by a vision of humanity "redeemed through art, forgiven, and reconciled with nature and the absolute." His influence on subsequent Western art music is profound. Beethoven wrote his own early compositions in the shadow of Mozart, of whom Joseph Haydn wrote that "posterity will not see such a talent again in 100 years."
