Così Fan Tutte contains some of Mozart’s most sublime music. On one level, the opera is purely a social anecdote about young people falling in and out of love; but Mozart was a supreme sensualist and a great humanist, and invested the tale with all his understanding of humanity and young love. In this title, David Timson refutes the charge that Mozart squandered his genius on a work full of trivial nonsense and proves this "miraculous yet problematic" opera to be a great work of theatre. To listen to this thought-provoking examination of the characters and the music is both thoroughly enriching and great fun.

Puccini’s swansong has a claim to being the last great popular opera. Its melodies have enchanted audiences since its posthumous premiere in 1926, two years after Puccini’s death. It involves a chilling story of love and cruelty, an intriguing cast of characters against the exotic backdrop of Imperial China, magnificent choruses and ensembles, and dazzling orchestration in an exotic score that comprises a string of remarkable arias - among which the great tenor aria "Nessun dorma" is the jewel. It is more than Puccini’s last opera: It is the last word, in every sense, on Italian opera.

La Traviata owes its enduring popularity to a superb story of young love and fatal sacrifice, set to music by Italy’s master melodist at the peak of his powers. Interest and poignancy are added by the fact that this is a true story - the baritone ‘heavy’ is Alexander Dumas who wrote The Count of Monte Cristo. But it is the central figure, the heroine Violetta, the archetypal ‘whore with the heart of gold’ who dominates the piece. It is her opera and we love her for it.

The Barber of Seville is Rossini’s most popular opera. Its effervescent overture (written originally for another work!) presents a perfect platform for the amusing plot in which the barber, Figaro, stage-manages a romance between Count Almaviva and Rosina, and puts to flight the old suitor, Dr Bartolo. "Largo al Factotum" is one of the most popular arias in opera - nearly 200 years after its first performance it is still one of the great show-stoppers.

Tchaikovsky declared that Mozart was 'full of divine beauty', and Schubert's wonder at the 'countless images of a brighter and better world' that Mozart was able to conjure up through his music knew no bounds. Many of us carry the image of Mozart as a transcendent genius, but what do we really know about his life and career, and indeed his music? This entertaining and informative biography takes us from Mozart's beginnings as a child prodigy to his greatest successes and cruellest setbacks.

Carmen is among the most popular operas for all the obvious reasons: great characters, a gripping story, and fabulous music. But what sets it on a pinnacle is an amazing combination of three factors: a sizzling Gipsy heroine (one of the most psychologically complex and compelling characters in all theatre), great atmosphere (Spain, hot sun, the bull-ring), and the prodigality of melodic invention - one great tune after another, at least a dozen of which are the staples of Madison Avenue and the animated cartoon.

Many opera-lovers would name The Marriage of Figaro as their favorite opera. It appeals to the most intellectual listener, but also to music-lovers seeking great melodies and ensembles (while it remains accessible through its fascinating plot and memorable characters) and to those seeking only entertainment. One of three operas by Mozart to libretti by Lorenzo da Ponte, it represents one of the pinnacles not just of operatic but of human achievement.

Tosca is Puccini at the peak of his theatrical power. The story of the jealous, impassioned opera singer Floria Tosca and her doomed love for the painter Mario Cavaradossi is played out against backgrounds both historically and geographically overwhelming. It is set in three great and historical locations of Rome during the Napoleonic era. Spectacle, sensuality, and cruelty battle for our attention in one of the most truly "action-packed" works of theatre. Enticing us with just a couple of the "great tunes" from this deeply affecting opera, David Timson then begins setting the biographical and operatic scene.

Verdi’s Falstaff repays careful study with real pleasure. It is opera’s happiest irony that the great Italian master should cap a career - distinguished for its blood-and-thunder tragic masterpieces - with the greatest comic opera in the Italian repertory. The genius of Shakespeare is harnessed (in a miracle of compression) by master-librettist Boito to give the 80-year-old Verdi a superb libretto, on which he lavished more wonderful tunes than most composers manage in a lifetime.

Wagner’s Ring cycle is the most ambitious work in the history of music: four operas that combine to tell a single epic story. Based in legend, it has become a legend in its own right: a supreme challenge for conductors, singers, opera producers, and indeed for audiences. But for all its grandeur and complexity, The Ring is far more accessible than many music lovers think.
