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.

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.

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.

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.

The Magic Flute almost defines a masterpiece, because it can be enjoyed on every level. It is a superb fairy story, complete with dragons, demons, a handsome prince, and a lovely maiden seriously in need of rescue; it is a political satire, social commentary, and psychological drama; it is full of tunes from the playful to the heart-stopping, jolly songs, and deeply spiritual outpourings. It is, in short, "Mozart" - and there is no greater compliment than that.

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.

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.

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.

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.

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.

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.

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.

Claude Debussy is regarded by many as the quintessential French composer, with music that invited both warm applause and frosty criticism in his day. While our ears no longer hear him as controversial, his works heralded the dawn of an artistic period founded on innovation and experiment, and a desire to break with the past in search of new expressive means. With never a dull moment, Debussy went from being a musical misfit at the Paris Conservatoire to bohemian life amongst the Symbolist poets and some scandalous love affairs.

The music of Bohemian composer Antonín Dvořák is suffused with natural nobility, fluency and freshness, and embodies the spirit of his native land. This revealing biography portrays Dvořák as a complex and wide-ranging composer, and explores the creation and performance of his music as well as its reception on both sides of the Atlantic, tracing his art in all its richness and variety.

La sonnambula was written by Bellini as a vehicle for two of the supreme singers of his age and accordingly is a fine example of the school we call bel canto, where beauty of voice and the virtuosity of the singers is integral to conveying the emotions in the soul of the composer. The fact that Bellini was one of the great melodists, writing long, beautiful vocal lines, that he was a master orchestrator and that he could write stirringly for the chorus all conspire to make La sonnambula extremely enjoyable.

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.

Rossini’s comic operas, like The Barber of Seville, are better known than his tragedies though he wrote in fact many more tragedies than comedies. One of them, his last, William Tell, is actually credited with launching the whole age of Grand Opéra. Tancredi is an early work - indeed his first smash hit - and it established his international fame.

Based on the simple yet deeply moving legendary tale of Orpheus, who loses his beloved wife to death but is able to restore her through the power of his music, Orfeo ed Euridice is among the earliest operas to hold a secure place in the repertory. Gluck lavishes a wealth of beautiful melody on this tale, whose appeal to composers is obvious; yet the abiding strength lies in the power and majesty of his inspiration, whether in the solos, the choruses, or the ballet music.

The Flying Dutchman is the perfect opera with which to approach the operatic mountain that is Richard Wagner. It is short, has a great story (the legend of the Dutch captain doomed to sail forever unless redeemed through love), and the striking score has many pre-echoes of Wagner's later great music dramas. It contains wonderful tunes in its arias, ensembles, and big choruses, and the orchestral writing - from the gale that blows out of the Overture to the final theme of "Redemption through Love" - will "blow you away".

Die Fledermaus is one of the few operatic works to which the phrase "never a dull moment" can be truthfully applied. From the explosive opening of the famous overture - reminiscent of a volley of champagne corks - through the surging energy of the "Fledermaus Waltz" and the many comic numbers, of which the accelerando trio is the finest, up to such huge concerted numbers as the "Duidu" finale to Act II, this is an operetta which almost incarnates nostalgia. Thomson Smillie and David Timson infuse their exploration of Die Fledermaus with as much life as the operetta itself.

The Great Gate of Kiev resounds to the tumultuous bell rings that end Pictures an an Exhibition, one of the most magnificent and virtuosic of all piano pieces. However, to some of his contemporaries, Modest Mussorgsky was ‘insane’ and ‘a perfect idiot’. Born into a wealthy land-owning family, what drove this tormented man and why did he suffer psychological breakdowns and alcoholism? How did he achieve his command of the realist idiom in his stage works? d, of course, Pictures at an Exhibition.

Felix Mendelssohn was a child prodigy to rival Mozart and achieved great fame during his lifetime, fêted across Europe, and composing in the widest possible range of musical genres. However, his music has also been denigrated for its elegance, charm and symmetry. This insightful biography explores the breadth of his achievements, the complexities of his privileged upbringing, and the reasons for the fluctuating nature of his reputation. Musical excerpts include the Violin Concerto, String Octet and Elijah, as well as his choral works, symphonies, sonatas and songs.

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.

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.

With the possible exception of Mozart, Verdi is the most popular opera composer who ever lived. Quite early in his career his tunes were being cranked out by barrel organs throughout Europe and were well known to many who may never even have heard his name. But the complex man behind them remains elusive and puzzling. In this portrait-in-sound, Jeremy Siepmann and a group of distinguished actors take an in-depth look behind the popular image of a man who was, and perhaps remains, the most enduring national hero in Italian history and a colossus in the history of music itself.
