He discovered that his sister, Susanna, possessed a beautiful and sympathetic voice, which by his instruction rapidly developed. Festing still continued to give him lessons on the violin, and calling in King Street one day for this purpose, he found Arne diligently practising with his music supported on the lid of a coffin. Horrified with the sight, he declared he could not play under such circumstances, as he would be constantly imagining there might be a corpse in the coffin beneath. "So there is," said Arne, and gave proof by removing the lid. In 1732, Arne's father dabbled in music as a business speculation; induced to do so, perhaps, by the remarkable talent of his children. He and others, without permission, and without consulting Handel, announced performances of that composer's works at the theatre in the Haymarket. An advertisement of May the 10th reads: "At the theatre in the Haymarket on Thursday the 12th inst. Acis and Galatea, a pastoral drama set by Mr. Handel will be performed, with all the choruses, songs, machines and other decorations: being the first time it ever was performed in a theatrical way. The part of Acis by Mr. Mountier, being the first time of his appearing in character on any stage. Galatea by Miss Arne. Pit and boxes at five shillings. Subscriptions are only taken in by Mr. Arne at the Crown and Cushion, King Street, Covent Garden." For some reason the performance did not take place on the 12th, but on the 17th. Dr. Burney says that the adventurers, or partners, in the speculation included Arne and his son, and the performers, Miss Arne and Miss Cecilia Young, afterward young Arne's wife. Arne now resolved to essay his powers in composition, by setting to music the libretto of Rosamond, written by Addison. The music of the chief character he designed for his sister, and the part of the Page for his young brother Michael. The work when completed was presented to the public at the theatre in Lincoln's Inn Fields on the 7th of March, 1733. In addition to his sister and brother, the performers were Mrs. Barbier; Leveridge, the veteran bass, Mr. Corfe, Mrs. Jones and Miss Chambers. The first performance proved a great success and was followed by ten others; the last was announced for the benefit of "_Mr. Arne, junior,_" evidently to distinguish the composer from the father. Thus encouraged Arne now determined to try his hand on a humorous composition, and selected for the purpose Fielding's Burletta "Tom Thumb"; this had been played as a comedy, with great success, in 1731, under the title "The Tragedy of Tragedies!" In its new musical dress the composer called it "The Opera of Operas," and it was submitted to the judgment of the public at the new theatre in the Haymarket on the 31st of May, 1733. The principal character, Tom Thumb, was personated by the composer's brother Michael. The verdict of the audience was highly favourable; the piece attained great popularity, and a very long run.
