String Musical Instruments
Erhu
The erhu is a very famous stringed instrument in China. Its history can
be traced back to the Tang
Dynasty (618-907). It was welcomed among the ethnic people of the
northeastern part of China. The erhu has long been the instrumental
accompaniment in traditional dramas.
The erhu's structure is quite simple. There is a slim neck about 80
centimeters, on the surface of which two strings are fixed. In addition, there
is a cup-shaped canister and a bow made of horsehair. While performing, the
musician is usually seated, with the organ and bow held in the left and right
hand respectively.
The range consists of three octaves. The somewhat melancholic tone is close
to the human voice and is good at conveying sad emotions. Some people call it
the Chinese violin.
The making, renovation, and performing skills of the erhu have been greatly
improved since 1949. It can be played solo or as an accompaniment in operas and
traditional dramas. In ethnic orchestras, the erhu even plays the leading role,
just as the violin does in Western orchestras.
The erhu is highly popular with the Chinese people because of its simple
design and low cost. Nearly every Chinese family loves it.
Gaohu
The gaohu is generally called the alt erhu, as it developed
from the erhu. Its development is closely linked to Cantonese music.
Cantonese music is usually performed with folk instruments. In the beginning,
there was no gaohu in Cantonese music. Around the 1920s, the Cantonese musician
and performer Lu Wencheng made great improvements to the erhu. He changed the
silk strings to steel ones, and raised the tones. When performing, he put the
canister between his legs. The gaohu soon became the leading instrument in
Cantonese music.
The material, making, and structure of the gaohu are similar to that of the
erhu. The biggest difference is the canister. Designers had few limits in making
the instrument. Some designers changed the round canister into a flat round one,
which raised the volume. Some changed it to a three-stringed instrument instead
of a two-stringed one, which expanded the range.
The gaohu has a clear and bright sound. Along with this characteristic, the
full-bodied bass part has been given great prominence in the band. As a rule,
the gaohu is given a highly valued seat in Chinese ethnic orchestras. In
addition, it is especially good at performing lively rhythms. For that reason,
it is often used to perform the accompaniment of theme songs.
