Wolfgang Amadeus Mozart (1756-1791) was an Austrian composer and piano virtuoso. He is recognized as a genius musician and phenomenal composer who composed both secular and sacred works. He was a child prodigy and from his childhood he gave concerts all over Europe. Among his most famous works are the operas The Marriage of Figaro and Don Giovanni, as well as the composition A Little Night Music and his last and unfinished funeral mass, Requiem in D minor (KV 626)

Franz Joseph Haydn (1732–1809) was an Austrian composer and one of the leading composers of the classical period, sometimes referred to as the "father of the symphony". Although Haydn did not invent a modern symphony, in his hands this form reached its rightful place thanks to his constant search for new methods of expression and his exceptional talent for melodic line and harmony. Haydn was popular among his peers mainly for his kindness and optimism. He excelled in his sense of humor, and his love of joking is often evident in his music. Haydn's work is stunning and numbers up to 2,000 works.
