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.

Jakob Ludwig Felix Mendelssohn Bartholdy born and widely known as Felix Mendelssohn, was a German composer, pianist, organist and conductor of the early Romantic period.

Mendelssohn is often compared to Mozart. Both of them were child prodigies, both had a talented sister and they both died at a young age. Mendelssohn, who as a child also painted wrote poetry, was born in small family which converted to christianity from judaism. As a composer he preferred looking back, rather than forward: his main examples were Bach, Handel and Mozart. It was Mendelssohn who retrieved Bach from oblivion and pushed for a revival of his music, which still lasts today. One century after its premier, Mendelsson performed the St Matthew Passion for the second time ever, in 1829.

Three years, earlier, on his 17th, he had already composed his masterfully overture A midsummer night's dream op. 21, based on Shakespeare's play. Today, it is still considered as one of the absolute masterpieces in all of the orchestra reperoire. His Violin Concerto op. 64 belongs to the most beautiful works of the 19th century as well. During his travels through Europe, he wrote his brilliant Italian Symphony, Scottish Symphony and the overture The Hebrides.

Although Mendelssohn had a prosperous career, his weak physique made him emotionally vulnerable. The death of his favourite sister Fanny became fatal: Mendelssohn died in the same year, at the age of 38.

Johann Strauss II was an Austrian violinist and composer of many waltzes and operettes. His father, the composer Johann Strauss sr., did not want him to become a musician. As a child, he studied in secret under his father's biggest rival's guidance, Joseph Lanner. Johann Strauss jr. could really focus on a career as a composer once Johnn sr. left the family. His two brothers, Josef and Eduard, were composers two, but Johann jr. was by far the most succesful. This led to an enormous jealousy among the brothers, especially with Eduard. Yet, musically too, Johann jr. was far better equipped then his two brothers. During his lifetime, he was already known as the king of waltzes and the growing popularity of the Viennese waltz is partly due to him as he was able to lift the genre from the regular dance halls to concert stages. He was regarded as one of the most prominent composers of his time, among others by Johannes Brahms who was a personal friend of his. At the age of 73, Strauss II died of pneumonia.

Jacques Offenbach was a German-born French composer of the Romantic period. He is remembered for his nearly 100 operettas of the 1850s–1870s and his uncompleted opera The Tales of Hoffmann. He was a powerful influence on later composers of the operetta genre, particularly Johann Strauss, Jr. and Arthur Sullivan. His best-known works were continually revived during the 20th century, and many of his operettas continue to be staged in the 21st. The Tales of Hoffman remains part of the standard opera repertory.
Born in Cologne, the son of a synagogue cantor, Offenbach showed early musical talent. At the age of 14, he was accepted as a student at the Paris Conservatoire but found academic study unfulfilling and left after a year. From 1835 to 1855 he earned his living as a cellist, achieving international fame, and as a conductor. His ambition, however, was to compose comic pieces for the musical theatre. Finding the management of Paris' Opéra-Comique company uninterested in staging his works, in 1855 he leased a small theatre in the Champs-Élysées. There he presented a series of his own small-scale pieces, many of which became popular.
In 1858, Offenbach produced his first full-length operetta, Orphée aux enfers ("Orpheus in the Underworld"), which was exceptionally well received and has remained one of his most played works. During the 1860s, he produced at least 18 full-length operettas, as well as more one-act pieces. His works from this period included La belle Hélène (1864), La Vie parisienne (1866), La Grande-Duchesse de Gérolstein (1867) and La Périchole (1868). The risqué humour (often about sexual intrigue) and mostly gentle satiric barbs in these pieces, together with Offenbach's facility for melody, made them internationally known, and translated versions were successful in Vienna, London and elsewhere in Europe.
