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.

L’elisir d’amore, or The Elixir of Love, has remained popular for almost two centuries because of a touching tale and a galaxy of comic characters adapted from the traditional commedia dell’ arte. Above all Donizetti poured into the score all the warmth and tenderness of the Italian temperament.

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.

Don Giovanni has long been regarded as Mozart’s supreme theatrical achievement. The subject seems unpromising - the last day in the life of the notorious womanizer Don Juan - but the skill of the librettist allied to the genius of Mozart at the very peak of his powers has created a work which is not only highly entertaining but reflects an incredible understanding of the human condition.

Cavalleria rusticana is the short opera that has all the elements of a grand opera compressed into a single highly dramatic time span. The story of love, lust, blood-feud, and betrayal played out against the pageantry of the Easter celebrations in a Sicilian village delivers an emotional wallop because of the youthful vigor and musical wealth of its great score which includes the glorious "Easter Hymn" and the deeply moving "Intermezzo". Mascagni was never to repeat his youthful success but this brief work is enough to ensure his immortality.

La Bohème is one of the three operas - the others are Carmen and Aida - believed to be the most popular ever written. In the case of La Bohème the reason is that it virtually defines the term "romantic". The poignant story of Mimì and Rodolfo is told in music of such tender beauty, allied, as always, to Puccini’s intuition of what works in the theatre. The result is an opera that readily appeals to our emotions and senses.

Ancient Egypt and the war with Ethiopia is the setting for Verdi’s grandest opera. It is the story of the love between Rhadames, the Egyptian general, and Aida, an Ethiopian slave, and the jealousy of Amneris, daughter of the King of Egypt. It was written in 1871 to a commission from the Khedive of Egypt to inaugurate the new opera house in Cairo. Aida generally is considered one of the most spectacular of Verdi’s operas.

Monteverdi’s Orfeo, first performed in 1607, generates a special excitement because it is the first unquestioned masterpiece of opera. Notable for its precise orchestration and powerful drama it was a groundbreaking work. It concerns the legend of Orpheus, the demigod whose music had the power to conquer the forces of Hell and to bring his wife back, briefly, to life. The extracts used in this introduction are from Naxos’ full recording; it uses authentic period instruments, which serve to evoke the early Baroque period of the opera’s composition.

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.

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.

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.

Rigoletto is simply wonderful entertainment with superb music. It is also much more - a daring (for its time) attack on aristocratic privilege, a tender love story, and an impassioned appeal on behalf of the disadvantaged, all set to music of such wealth and beauty that, with its sister operas La traviata and Il trovatore, it has defined Italian opera for 150 years. Overcoming initial trouble with the censors, Verdi's Rigoletto was a smash hit at its premiere and has not been out of the repertoire since. It’s not hard to see why.

Tristan und Isolde centres around two lovers who dream of romantic love and yearn for oblivion. No composer had written such a work before. Turning his back on traditional tonality, Wagner changed the course of Western music with Tristan und Isolde. But there’s also fact behind the fiction: while he wrote his opera Wagner was in love with another’s man’s wife, Mathilde Wesendonk. So Tristan and Isolde are also Richard and Mathilde.

Pagliacci may be the most completely compelling short opera in the repertory and owes much of its impact to a brilliant story based, it is said, on true life and told through the device of a play-within-a-play. The action is set in Calabria in the deep south of Italy where the jealousies and illicit passions of a troupe of strolling actors precisely intersect with the play they are performing - to both touching and tragic effect.

Il Trovatore has been ruthlessly parodied. It is a tale of murder and mayhem, burned babies, roasted hags, would-be nuns, strolling minstrels, and bad baritones. And indeed the libretto does call for a willing suspension of disbelief. The reward is in the music, a score as prodigally melodic as only the mature Verdi could write: the "Anvil" chorus, the "Miserere" scene, two great tenor arias, a beautiful baritone aria - a richness without embarrassment.
