La Scala (Italian: Teatro alla Scala), is a world renowned opera house in Milan, Italy. The theatre was inaugurated on 3 August 1778 and was originally known as the New Royal-Ducal Theatre at La Scala (Italian: Nuovo Regio Ducale Teatro alla Scala). The premiere performance was Antonio Salieri's Europa riconosciuta.

Most of Italy's greatest operatic artists, and many of the finest singers from around the world, have appeared at La Scala during the past 200 years. Today, the theatre is still recognised as one of the leading opera and ballet theatres in the world and is home to the La Scala Theatre Chorus, La Scala Theatre Ballet and La Scala Theatre Orchestra. The theatre also has an associate school, known as the La Scala Theatre Academy (Italian: Accademia Teatro alla Scala), which offers professional training in music, dance, stage craft and stage management.

La Scala's season traditionally opens on 7 December, Saint Ambrose's Day, the feast day of Milan's patron saint. All performances must end before midnight, and long operas start earlier in the evening when necessary.

Gioachino Antonio Rossini (Italian pronunciation: [dʒoaˈkiːno anˈtɔːnjo rosˈsiːni] (Giovacchino Antonio Rossini in the baptismal certificate) (29 February 1792 – 13 November 1868) was an Italian composer who wrote 39 operas as well as sacred music, chamber music, songs, and some instrumental and piano pieces. His best-known operas include the Italian comedies Il barbiere di Siviglia (The Barber of Seville) and La Cenerentola and the French-language epics Moïse et Pharaon and Guillaume Tell (William Tell). A tendency for inspired, song-like melodies is evident throughout his scores, which led to the nickname "The Italian Mozart". Until his retirement in 1829, Rossini had been the most popular opera composer in history.

Gioachino Antonio Rossini was born into a family of musicians in Pesaro, a town on the Adriatic coast of Italy which was then part of the Papal States. His father, Giuseppe, was a horn player and inspector of slaughterhouses. His mother, Anna, was a singer and a baker's daughter. Rossini's parents began his musical training early, and by the age of six he was playing the triangle in his father's musical group.

Sir Georg Solti, KBE,  /ˈdʒɔrdʒ ˈʃɒlti/ (21 October 1912 – 5 September 1997) was an orchestral and operatic conductor, best known for his appearances with opera companies in Munich, Frankfurt and London, and as a long-serving music director of the Chicago Symphony Orchestra. Born in Hungary, he studied in Budapest with Béla Bartók, Leo Weiner and Ernő Dohnányi. In the 1930s, he was a répétiteur at the Hungarian State Opera and worked at the Salzburg Festival for Arturo Toscanini. His career was interrupted by the rise of the Nazis, and because he was a Jew he fled the increasingly restrictive anti-semitic laws in 1938. After conducting a season of Russian ballet in London at the Royal Opera House he found refuge in Switzerland, where he remained during the Second World War. Not permitted to conduct there, he earned a living as a pianist.

After the war Solti was appointed musical director of the Bavarian State Opera in Munich from 1946. In 1952 he moved to the Frankfurt Opera, where he remained in charge for nine years. He took German citizenship in 1953. In 1961 he became musical director of the Covent Garden Opera Company in London. During his ten-year tenure, he introduced changes that saw standards raised to the highest international levels. Under his musical directorship the status of the company was recognised with the grant of the title "the Royal Opera". He became a British subject in 1972.

Sergiu Celibidache (Romanian pronunciation: [ˈserd͡ʒju t͡ʃelibiˈdake]; 28 June 1912 – 14 August 1996) was a Romanian conductor.

Celibidache was born in Roman, Romania, and began his studies in music with the piano, after which he studied music, philosophy and mathematics in Bucharest, Romania and then in Paris. One of the most important influences in his life was his introduction to Martin Steinke, who, being knowledgeable about Buddhism, heavily affected Celibidache's outlook for the rest of his life.

Sergiu Celibidache studied in Berlin and, from 1945 to 1952, he was principal conductor of the Berlin Philharmonic. He later worked with radio orchestras in Stockholm, Stuttgart and Paris. He also worked in Britain in the late 1940s and 1950s, due partly to the promotional efforts of the pianist Eileen Joyce and her partner, an artists' agent. Joyce said that Celibidache was the greatest conductor she had ever worked with - "he was the only one who got inside my soul". In 1970 he was awarded Denmark's Sonning Award. From 1979 until his death he was music director of the Munich Philharmonic. He regularly taught at Mainz University in Germany and in 1984 taught at the Curtis Institute in Philadelphia, Pennsylvania. Teaching was a major focus throughout his life and his courses were frequently open to all without fee. Among his notable students are Françoys Bernier, Jordi Mora, Peter Perret, and Markand Thakar.

Carlo Maria Giulini (Italian pronunciation: [ˈkarlo maˈriːa dʒuˈliːni]; May 9, 1914 – June 14, 2005) was an Italian conductor.

Giulini was born in Barletta, Italy, to a father born in Lombardy and a mother born in Naples; but he was raised in Bolzano, which at the time of his birth was part of Austria (it was given to Italy in the Treaty of London (1915)). Therefore, most of the neighbors spoke a dialect of German, and the local music he heard tended to be Austrian/ Tyrolean. He recalled being transfixed by the town band.

Giulini was given a violin for Christmas in 1919, when he was five, and progressed rapidly with local instructors, notably a Bohemian violinist (and local pharmacist) whom he called "Brahms." In 1928, the distinguished Italian violinist/composer Remy Principe (1889–1977) gave a recital in Bolzano, and auditioned Giulini; he invited Giulini to study with him at Italy's foremost conservatory, the Accademia Nazionale di Santa Cecilia in Rome. Giulini undertook his studies there two years later, at the age of 16. He studied viola with Principe, composition with Alessandro Bustini (1876–1970), and conducting with Bernardino Molinari.
