Royal Academy of Music (1719–34)

In May 1719, The 1st Duke of Newcastle, the Lord Chamberlain, ordered Handel to look for new singers. Handel travelled to Dresden to attend the newly built opera. He saw Teofane by Antonio Lotti, and engaged members of the cast for the Royal Academy of Music, founded by a group of aristocrats to assure themselves a constant supply of baroque opera or opera seria. Handel may have invited John Smith, his fellow student in Halle, and his son Johann Christoph Schmidt, to become his secretary and amanuensis. By 1723 he had moved into a Georgian house at 25 Brook Street, which he rented for the rest of his life. This house, where he rehearsed, copied music, and sold tickets, is now the Handel House Museum. During twelve months between 1724 and 1725, Handel wrote three successful operas, Giulio Cesare, Tamerlano and Rodelinda. Handel's operas are filled with da capo arias, such as Svegliatevi nel core. After composing Silete venti, he concentrated on opera and stopped writing cantatas. Scipio, from which the regimental slow march of the British Grenadier Guards is derived, was performed as a stopgap, waiting for the arrival of Faustina Bordoni.

In 1727, Handel was commissioned to write four anthems for the Coronation ceremony of King George II. One of these, Zadok the Priest, has been played at every British coronation ceremony since. The words to Zadok the Priest are taken from the King James Bible. In 1728, John Gay's The Beggar's Opera, which made fun of the type of Italian opera Handel had popularised in London, premiered at Lincoln's Inn Fields Theatre and ran for 62 consecutive performances, the longest run in theatre history up to that time. After nine years the Royal Academy of Music ceased to function but Handel soon started a new company.

The Queen's Theatre at the Haymarket (now His Majesty's Theatre), established in 1705 by architect and playwright John Vanbrugh, quickly became an opera house. Between 1711 and 1739, more than 25 of Handel's operas premièred there. In 1729, Handel became joint manager of the theatre with John James Heidegger.

Handel travelled to Italy to engage new singers and also composed seven more operas, among them the comic masterpiece Partenope and the "magic" opera Orlando. After two commercially successful English oratorios Esther and Deborah, he was able to invest again in the South Sea Company. Handel reworked his Acis and Galatea which then became his most successful work ever. Handel failed to compete with the Opera of the Nobility, who engaged musicians such as Johann Adolph Hasse, Nicolo Porpora and the famous castrato Farinelli. The strong support by Frederick, Prince of Wales caused conflicts in the royal family. In March 1734 Handel composed a wedding anthem This is the day which the Lord hath made, and a serenata Parnasso in Festa for Anne, Princess Royal.

Despite the problems the Opera of the Nobility was causing him at the time, Handel's neighbour in Brook Street, Mary Delany, reported on a party she invited Handel to at her house on 12 April 1734 where he was in good spirits:

I had Lady Rich and her daughter, Lady Cath. Hanmer and her husband, Mr. and Mrs. Percival, Sir John Stanley and my brother, Mrs. Donellan, Strada and Mr. Coot. Lord Shaftesbury begged of Mr. Percival to bring him, and being a profess'd friend of Mr. Handel (who was here also) was admitted; I never was so well entertained at an opera! Mr. Handel was in the best humour in the world, and played lessons and accompanied Strada and all the ladies that sang from seven o'clock till eleven. I gave them tea and coffee, and about half an hour after nine had a salver brought in of chocolate, mulled white wine, and biscuits. Everybody was easy and seemed pleased.
