Description:
The gu-zheng is a long zither in who is classified as “plucked silk
instrument” and it is a member of the chordophone family. This family of long
zithers includes the Korean Kayagum, Japanese Koto and the Vietnamese Dan-Tranh they are all off shoots from an ancient
zither called a Qin-zheng.
The gu-zheng dates back to the Qin
Dynasty “warring states period" (475-211 BC) circa 2500 years ago. In
Chinese the word “gu” translates as “ancient” and "zheng" means to
argue. In the Eastern Han Dynasty (25 AD to 220AD) the gu-zheng was documented
in vivid detail, a scholar named Hou Jin wrote that the sounds of the gu-zheng
can reach the heavens and the spirits below. The gu-zheng remained very popular
with the courts and amongst the common people.
Upon the arrival of the Tang Dynasty
(618-907 AD) the amount of strings for the zheng increased. In the Qing Dynasty
(1644-1911 AD) the gu-zheng remained very popular. In the Ming Dynasty
[1368-1644] a fifteenth string was added. In 1948 Prof. Cao Zheng was
innovative in spearheading the development of music instructional programs that
offer courses to study the zheng in universities, now these courses are
commonly available in universities. In contemporary China the gu-zheng
is being incorporated into many different genres Classical, Jazz, Chinese Rock
n' role, cinema scores and experimental music’s.
A legend About the Zheng: There is a legend about a master se player his two sons
were arguing over a se (25-string zheng) that his sons were to inherit after he
passed on. As the master became old he was sad to see his two sons constantly
argue all the time over his se. To settle the dispute he split the “se” into
two 13-stringed zhengs in return this resolved the argument. The character for
zheng makes up for two symbolisms the first meaning bamboo and the other
meaning "to argue". After splitting the “se” the old master was very
pleased and he noted the tone was more crisp then the se.
Playing Techniques:
They include note bending with the three fingers of the left hand to
right hand, roles, playing includes the use of tortoise shell plectrums
each plectrum is wrapped with tape around the thumb, pointy and middle
fingers are used these plectrums produce a very clean and crisp tone.
Often the left hand works independently from the right hand. The zheng
is tuned in a pentatonic 5-note scale C, D, E, G, A, C there are several tunings.
Anatomy of the Gu-Zheng: The gu-zheng can have up to 21 to 25 strings however the 21
string gu-zheng's are the current standard. Since ancient times the gu-zheng
was strung with silk strings and in the 2nd century the gu-zheng was equipped
with jade bridges. Nowadays gu-zhengs are` strung with nylon or steel strings.
The body of the gu-zheng is made of Paulownia elongata or wu-tong wood. On the
surface of the zheng at the left and right ends "bas relief" artwork
is displayed. The theme depicts cranes flying throughout the sky. Cranes are
considered sacred amongst many Asian cultures. The top surface of the zheng is
curved while the bottom is flat. Two collapsible stands are made for the
gu-zheng as you see in the photo. The tuning pins are protected inside a
recessed container.
