The British National Opera Company presented opera in English in London and on tour in the British provinces between 1922 and 1929. It was founded in December 1921 by singers and instrumentalists from Sir Thomas Beecham's Beecham Opera Company (1915-1920), which was disbanded when financial problems over buying The Bedford Estate forced Beecham to withdraw from the music scene for a short period. The new venture was financed by the issue of 40,000 preference shares at £1 each. Among the musicians who met at the inaugural meeting of the new enterprise at the Queen's Hall were Sir Alexander Mackenzie, Sir Charles Stanford, Harry Plunket Greene, Aylmer Buesst and Sir Henry Hadow. The new company bought the entire assets of the Beecham company, comprising the scenery, costumes, scores, instruments and performing rights for 48 operas.
The company's first performance was Aida at Bradford in February 1922, and received excellent notices. For much of its existence the company toured in the provinces, but also had short seasons at Covent Garden (1922–1924) and then at His Majesty's Theatre. For the 1923 Covent Garden season Dame Nellie Melba emerged from retirement to sing with the company. She gave her services free of charge, to support the company. She did not, however, feel equal to relearning her old roles in English translation, and she sang in Italian while the rest of the company sang in the vernacular.
The British National Opera Company was a pioneer of broadcast opera, with excerpts from The Magic Flute broadcast live from the Royal Opera House by the British Broadcasting Company in January 1923, less than a year after the foundation of both the BBC and the opera company.
