Chinese plucked string instrument

The ruan is a traditional Chinese plucked string instrument. It is a lute with a fretted neck, a circular body, and four strings. Its four strings were formerly made of silk but since the 20th century they have been made of steel (flatwound for the lower strings). The modern ruan has 24 frets with 12 semitones on each string, which has greatly expanded its range from a previous 13 frets. The frets are commonly made of ivory or in recent times of metal mounted on wood. The metal frets produce a brighter tone as compared to the ivory frets. It is sometimes called ruanqin, particularly in Taiwan.

The instrument can be played using a plectrum similar to a guitar pick (formerly made of animal horn, but today often plastic), or using a set of two or five acrylic nails that are affixed to the fingers with adhesive tape. Mainstream ruan players use plectrums, though there are some schools which teach the fingernail technique, similar to that of the pipa. Pipa players who play ruan as a second instrument also often use their fingernails. Plectrums produce a louder and more clear tone, while fingernails allow the performance of polyphonic solo music. The instrument produces a mellow tone. In Chinese orchestras, only the zhongruan and daruan are commonly used, to fill in the tenor and bass section of the plucked string section. Occasionally the gaoyinruan is used to substitute the high pitched liuqin. Daruan soloists generally use the D A D A tuning, as it allows for the easy performance of diatonic chords. Some orchestral players tune to C G D A, which is exactly the same as cello tuning. The advantage of using C G D A in orchestras is so that the daruan can easily double the cello part. A ruan ensemble (重奏) consists of two or more members of the ruan family, for instance, an ensemble of the xiaoruan, zhongruan and daruan. The wide range covered by the ruan, its easily blended tone quality, and the variety of soprano, alto, tenor, bass, and contrabass instruments all make ruan ensembles very effective in playing polyphonic music.

A small pipa was found in murals of tombs in Liaoning (遼寧) province in northeastern China. The date of these tombs is about late Eastern Han (東漢) or Wei (魏) period (220–265 AD). However, the pear shaped pipa was not brought to China from Dunhuang (敦煌, now in northwestern China) until the Northern Wei period (386–524 AD) when ancient China traded with the western countries through the Silk Road (絲綢之路). Evidence was shown on the Dunhuang Caves frescoes that the frescoes contain a large number of pipa, and they date to 4th to 5th century. During the Han period (206 BC 220 AD), Lady Wang Zhaojun (王昭君, known as one of the Four Beauties [四大美人] in ancient China) departed mainland to the west and married the Grand Khan of the Huns. The marriage was meant to maintain peace between the two ancient countries. On her way to the west, she carried a pipa on the horse. Looking back today, her pipa must have been a ruan type instrument with a round sound box, since the pear shaped pipa was not brought to China until the Northern Wei dynasty after the Han dynasty. However, in almost all the portraits and dramas, Lady Zhaojun's pipa is displayed inaccurately. The pipa is usually shown with a pear shaped sound box (as in today's pipa), rather than a round sound box. Note that the frets on all Chinese lutes are high so that the fingers never touch the actual body—distinctively different from western fretted instruments. This allows for a greater control over timbre and intonation than their western counterparts, but makes chordal playing more difficult.

In addition to the plucked ruan instruments mentioned above, there also exist a family of bowed string instruments called lāruǎn and dalaruan (literally "bowed ruan" and "large bowed ruan"). Both are bowed bass register instruments designed as alternatives to the gehu and diyingehu in large orchestras of Chinese traditional instruments. These instruments correspond to the cello and double bass in range. Chinese orchestras currently using the laruan and dalaruan include the China National Traditional Orchestra and Central Broadcasting National Orchestra, the latter formerly conducted by the late maestro Peng Xiuwen (彭修文).
