Instrumentation
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.
Guangdong music gradually evolved into a string ensemble format by the 1960s, led by the gaohu with ruan, qinqin, yangqin, sanxian, yehu, tiqin and various woodwind (including houguan) and percussion instruments. Alto saxophone, xylophone, violin, piano, electric guitar, and drum set may also be used, in combination with traditional instruments.
