Guangdong music, also known as (廣東音樂 "Kwongdong yam ngok",Guǎngdōng yīnyuè) is a style of traditional Chinese instrumental music from Guangzhou and surrounding areas in Pearl River Delta of Guangdong Province on the southern coast of China. The name of the music is not an accurate description because Guangdong music is not the only music of the whole Guangdong area. Cantonese classical music especially were usually much livelier in pace and happier then those of other China provinces which is typical and the very essence of the Cantonese's character. In Guangdong, there are numerous traditional genres of music such as Teochew music and Hakka music (Hakka Hanyue and sixian). The name of the music originated in the 1920 and 1930s when the music was popular in Shanghai ballrooms in the form of "Spiritual Music" (, Jīngshěn Yīnyuè; more properly translated as "spirited music"). As the performers were almost entirely from Guangdong, Shanghai people generalized the form of music as Guangdong music. Musically, compositions are based on tunes derived from Cantonese opera, together with new compositions from the 1920s onwards. Some pieces have influences from jazz and Western music, using syncopation and triple time, and incorporating instruments such as the saxophone, violin, guitar, piano, drum set, or xylophone.
The gaohu is the most common lead instrument used in performing Cantonese music. It was invented by Lü Wencheng (吕文成, 1898-1981) in the 1920s. Prior to this, the erxian was the most common lead bowed string instrument in the Cantonese ensemble. Ensembles led by the erxian and also featuring the tiqin are called yinggong (硬弓, literally "hard bow") ensembles, while those led by the gaohu are called ruangong (软弓, literally "soft bow") because the erxian and tiqin have thick bamboo bows, while the gaohu has a thinner, flexible bow.
