Wolfgang Amadeus Mozart, whose actual name is Joannes Chrysotomus Wolfgangus Theophilus Mozart, was a composer, pianist, violinist and conductor from the classical period, born in Salzburg. Mozart was a child prodigy. Already competent on keyboard and violin, he composed from the age of five and performed before European royalty. Along with Johann Sebastian Bach and Ludwig van Beethoven, Mozart is considered to be one of the most influential composers of all of music's history. Within the classical tradition, he was able to develop new musical concepts which left an everlasting impression on all the composers that came after him. Together with Joseph Haydn and Ludwig van Beethoven he is part of the First Viennese School. At 17, Mozart was engaged as a musician at the Salzburg court, but grew restless and traveled in search of a better position. From 1763 he traveled with his family through all of Europe for three years and from 1769 he traveled to Italy and France with his father Leopold after which he took residence in Paris. On July 3rd, 1778, his mother passed away and after a short stay in Munich with the Weber family, his father urged him to return to Salzburg, where he was once again hired by the Bishop. 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 portions of the Requiem, which was largely unfinished at the time of his death.

Johann Sebastian Bach was a German composer and musician of the Baroque period. He enriched established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include the Brandenburg Concertos, the Goldberg Variations, the Mass in B minor, two Passions, and hundreds of cantatas. His music is revered for its technical command, artistic beauty, and intellectual depth.

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

Frédéric Chopin is one of the greatest composers of the Romantic piano tradition. He was a master in making the small form great. His ballades, mazurkas, polonaises, preludes, etudes and nocturnes all belong to the most popular standard works for piano ever written. As a child prodigy, Chopin grew up in a middle class family, who lived among the literati of Warsaw. When in 1830 the November Uprising broke out in Poland, the twenty year old Chopin stayed in Vienna. He became an exile and never returned to his mother country. He eventually settled in Paris. He avoided public concerts, but he did like performing in small settings, such as salons and at home for his friends. This way, Chopin built a reputation as an exceptional pianist, teacher and composer.
Chopin brought a unique synthesis between the Viennese bravado and the French/English lyric style. Even though his pieces often are technically very demanding, the focus was always on creating a lyric expression and poetic atmosphere. He invented the instrumental ballade, and brought salongenres to a higher level with his many innovations and refinements.
