Alfred George Deller, CBE (31 May 1912 – 16 July 1979), was an English singer and one of the main figures in popularising the return of the countertenor voice in Renaissance and Baroque music during the 20th century.
[1] His style in singing lute song, with extensive use of rubato and extemporised ornamentation, was seen as radical and controversial in his day but is now considered the norm.
From this choral tradition, Deller emerged as a soloist, largely as a result of the admiration of the composer Michael Tippett, who heard him while at Canterbury and recognised the unique beauty of his voice.
The group recorded music from as early as the 13th century and significantly expanded popular notions of the Baroque repertoire, producing high-quality authentic period performances of the works of Bach, Handel, Purcell, Dowland, and even folk songs.
Membership of the Deller Consort changed over the years, particularly the top line (sopranos April Cantelo, Honor Sheppard and Mary Thomas.
[1] Britten wrote this role with Deller specifically in mind, although he was dropped from staged revivals of the work against the composer's wishes, largely because of poor acting technique.
The 1960 premiere, broadcast by the BBC, is now commercially available and finds Deller in fresher voice; Myfanwy Piper described his singing of Oberon as "unearthly".
Lutenist Desmond Dupré performed with him, initially as a guitarist; other accompanists included harpsichordist and musicologist Walter Bergmann.
Another son, Simon, trained as a music teacher during the 1960s and taught at Guildford Cathedral choir school, eventually becoming its headmaster.
