Frank Mullings (born in Walsall on 10 March 1881 – died in Manchester on 19 May 1953) was a leading English tenor with Sir Thomas Beecham's Beecham Opera Company and its successor, the British National Opera Company, during the 1910s and 1920s. Blessed with a strong stage presence and a voice that provoked varying reactions from critics, his repertoire included such taxing dramatic parts as Tristan in Tristan und Isolde, Radames in Aida, the title role in Otello, and Canio in Pagliacci. The limitations of early microphones meant that his voice was not always recorded successfully, although the British National Opera Company website notes that playing the recordings at 80 rpm produces a more reliable result.
The young Mullings studied singing in Birmingham and made his operatic début in Coventry in 1907—in Faust by Gounod. He joined the Denhof Opera Company in 1913, was engaged by the Beecham Opera Company from 1916 to 1921, and was with the British National Opera Company from 1922 until its closure in 1929. He was the first to sing the part of Wagner's Parsifal in English, which he did at the Royal Opera House, Covent Garden, in 1919.
Mullings was a noted interpreter, in England at least, of Verdi's Otello, as well as Tristan by Wagner. He created the role of Hadyar in Nail by Isidore de Lara, and the role of Apollo in Alkestis by Rutland Boughton.
