20th-century Vietnamese singers

NSND Trần Hiếu (23 April 1936) is a Vietnamese classical singer. With the late Quý Dương and Trung Kiên, Hiếu was counted as the 3C Trio (Vietnamese Tam ca 3C, from tam ca 3 “cụ”), a term modelled on the Three Tenors.

NSND Nguyễn Trung Kiên (Kiến Xương, Thái Bình, 1939 – 27 January 2021) is a Vietnamese classical singer and People's Artist. With the late Quý Dương and Trần Hiếu, Kiên was counted as the 3C Trio (Vietnamese Tam ca 3C, from tam ca 3 “cụ”) - a term modelled on the Three Tenors.

NSND Nguyễn Thị Thanh Hiền, also known by the stage name Thu Hiền (Đông Hưng, Thái Bình, 3 May 1952) is a Vietnamese traditional singer. She began by singing revolutionary songs, touring with field music troupe during the Vietnam War. Her performances mix accompaniment of traditional instruments such as đàn bầu and western keyboards.

NSND Lê Dung (5 June 1951 in Hòn Gai, Quảng Ninh – 29 January 2001 in Hanoi) was a Vietnamese soprano opera singer. She was a student at the Tchaikovsky Conservatory and toured and performed widely in Eastern Europe. She won prizes at Sofia, Bulgaria 1987, Toulouse 1988 and Pyongyang. She was a member of the Hanoi Opera but also sang and recorded the works of Phú Quang and other popular songwriters. In 1993, she became the youngest ever person to be accredited as People's Artist ("NSND"), Vietnam's top artistic award for a living artist - second only to the often posthumous Ho Chi Minh Prize.

NSND Phạm Quý Dương (Hải Dương, 1937 - 28 June 2011 at Hanoi) was a Vietnamese classical singer, and vocal coach at the Vietnam National Academy of Music. He was selected by Russian voice coaches as the singer to sing the lead baritone role in Tchaikovsky's Eugene Onegin (opera) at the Hanoi Opera in 1960, thus becoming Vietnam's first opera singer. He completed his training with Belcanto arias, some of which had been retained in the opera's repertoire from the French colonial period. In later years, together with NSND Trần Hiếu and NSƯT Trung Kiên, Quý Dương was counted as one of those affectionately known as the "3C Trio" (Vietnamese Tam ca 3C, from tam ca 3 “cụ”, old) - a term loosely modelled on Europe's Three Tenors, though the three did not perform as a trio.
