Hwang gave her professional solo debut with the English National Baroque Chamber Orchestra at the age of nine, performing Johann Sebastian Bach's Concerto in A minor, and in the same year performed for legendary violinist Ivry Gitlis in London.
Three years later, at the age of 12, she performed Nigel Hess's Ladies in Lavender with the Royal Philharmonic Orchestra.
She has appeared many times on live television and radio through the BBC and ITV, and in 2012, she was featured in a BBC4 documentary about the nation’s favourite composition The Lark Ascending by Ralph Vaughan Williams.
Her performance of this work was specifically chosen by the BBC to represent this timeless classic of the great British composer.
Among numerous other public performances, Hwang has particularly enjoyed her concerts for charity work and also playing at Clifton College's Proms on the Close, performing alongside world-class musicians José Carreras, Oscar Osicki, Lesley Garrett and Russell Watson.
