Soundboard The typically has a round
soundboard with no sound-hole, but inside the sound box are one or more strands of wire attached only at one end, so that they vibrate, giving the instrument a particular timbre and resonance. Occasionally, the body of the may be octagonal in shape.
Frets The has a short fretted neck. 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. The frets were formerly arranged rather like those on a
mountain dulcimer, so that the instrument is diatonic; however, the fret size is high enough that any pitch may be bent up a minor 3rd. Modern have frets tuned in semitones.
Strings Most have four strings, although others have two or three. used for
Beijing opera have two strings, only one of which is actually used, the lower string being there purely for sympathetic resonance. In
Taiwan, the has a longer neck, and two or three strings. The strings on the traditional form of the instrument were made of silk, though nylon is generally used today. The anchor on a modern may have up to five holes, so it can be strung and tuned as a three or four-stringed instrument. The nut, at the peghead end of the instrument, is filed with notches appropriate to the number and position of the strings. There is no bridge or saddle; the strings are simply attached to the anchor at the base of the instrument.
Tuning The strings are tuned in courses of two (each pair of strings is tuned to a single pitch), generally tuned to the interval of a perfect fifth. Three-string instruments are often tuned A D. Four-string instruments are often tuned to A D a d; however, in recent practice, the instrument is tuned G D g d so modern
liuqin and
ruan players can easily double on .
Plectrum and picks A long, sharp plectrum is often used to play the , which is sometimes attached to the instrument with a piece of cord. In Beijing opera, the player uses a small wooden dowel instead of a plectrum to perform, and only plays in first position; this requires the performer to use
octave displacement in order to play all the pitches within a given melody. Modern are often played with a
guitar pick. == Compared with the ==
