During the performance of qin, musicians may use a variety of techniques to reach the full expressing potential of the instrument. There are many special tablatures that had developed over the centuries specifically dedicated to qin for their reference and a repertoire of popular and ancient tunes for their choice.
Playing technique The tones of qin can be categorized as three characteristic "sounds". The first type is
san yin (), which literally means "unfettered sound". It's the fundamental frequency produced by plucking a free string with the fingers of the right hand. The second type, made by plucking a string with the right hand and gently tapping specific note positions on the string with the left hand, will create a crisp sound named
fan yin (, lit. "floating sound") or overtone
harmonics (the equivalent technique in Western music is the
string harmonic or
flageolet). Important scale notes, called
hui (), are marked by 13 glossy white dots made of mica or seashell inset in the front surface of the qin, occur at integer divisions of the string length. The "crystal concordant" (perfectly harmonic) overtones can only be evoked by tapping the strings precisely at these
hui. The third type is
an yin (, lit. "pressed sound"), which is sometimes also called
shi yin (, lit. "full sound") or
zou yin (, lit. "changing sound"). These comprise the major cadences of most qin pieces. To play
an yin, the musician stops a string at a specific pitch on the board surface with the left thumb, middle or ring finger, strikes the string with the right hand, then they may slide the left hand up and down to vary the note. This technique is similar to playing a
slide guitar across the player's lap. However, the manipulation of qin is much more multifarious than that of a guitar, which has only around 3 or 4 main techniques. (). According to the book
Cunjian Guqin Zhifa Puzi Jilan, there are around 1,070 different finger techniques used for the qin. Thus the qin is possibly the instrument with the most playing techniques in both the Chinese and Western instrument families. Most of the qin's techniques are obsolete, but around 50 of them still appear in modern performance. Sometimes, guqin can be played with a violin
bow. It has a tone similar to that of a
cello, but raspier. Image:Qintech Tiao.PNG| Tiao Image:Qintech Gou.jpg| Gou Image:Qintech Pi.PNG| Bo Image:Qintech Bo.jpg| Bo The above four figures are from an old handbook.
Tablature and notation {{Listen|type=music|header=The recordings below were made in 2013 Written qin music did not directly tell what notes were played; instead, it was written in a
tablature detailing tuning, finger positions, and stroke technique, thus comprising a step by step method and description of how to play a piece. Some tablatures do indicate notes using the
gongche system, or indicate
rhythm using
dots. The earliest example of the modern
shorthand tablature survives from around the twelfth century CE. An earlier form of music notation from the Tang era survives in just one manuscript, dated to the seventh century CE, called
Jieshi Diao Youlan (
Solitary Orchid in Stone Tablet Mode). It is written in a
longhand form called
wenzi pu () (literally "written notation"), said to have been created by Yong Menzhou during the
Warring States period, which gives all the details using ordinary written
Chinese characters. Later in the
Tang dynasty, Cao Rou and others simplified the notation, using only the important elements of the characters (like string number, plucking technique,
hui number and which finger to stop the string) and combined them into one character
notation. This meant that instead of having two lines of written text to describe a few notes, a single character could represent one
note, or sometimes as many as nine. This notation form was called
jianzi pu () (literally "reduced notation") and it was a major advance in qin notation. It was so successful that from the
Ming dynasty onwards, a great many
qinpu () (qin tablature collections) appeared, the most famous and useful being "Shenqi Mipu" (The Mysterious and Marvellous Tablature) compiled by
Zhu Quan, the 17th son of the founder of the Ming dynasty. In the 1960s, Zha Fuxi discovered more than 130 qinpu that contain well over 3360 pieces of written music. However, many qinpu compiled before the Ming dynasty are now lost, and many pieces have remained unplayed for hundreds of years.
Repertoire notation next to the qin tablature to indicate beats and notes. Qin pieces are usually around three to eight minutes in length, with the longest being "Guangling San", which is 22 minutes long. Other famous pieces include "Liu Shui" (Three Refrains on the Yang Pass Theme), "Meihua San Nong" (Three Variations on the
Plum Blossom Theme), "Xiao Xiang Shui Yun" (Mist and Clouds over the Xiao and Xiang Rivers), and "Pingsha Luo Yan" (
Wild Geese Descending on the Sandbank). The average player will generally have a repertoire of around ten pieces which they will aim to play very well, learning new pieces as and when they feel like it or if the opportunity arises. Players mainly learn popular well-transcribed versions, often using a recording as a reference. In addition to learning to play established or ancient pieces very well, highly skilled qin players may also
compose or
improvise, although the player must be very good and extremely familiar with the instrument to do this successfully. A number of qin melodies are
program music depicting the natural world.
Transcription Dapu () is the
transcribing of old tablature into a playable form. Since qin tablature does not indicate
note value,
tempo or
rhythm, the player must work it out for themselves. Normally, qin players will learn the rhythm of a piece through a teacher or master. They sit facing one another, with the student copying the master. The tablature will only be consulted if the teacher is not sure of how to play a certain part. Because of this, traditional qinpu do not indicate them (though near the end of the Qing dynasty, a handful of qinpu had started to employ various rhythm indicating devices, such as dots). If one did not have a teacher, then one had to work out the rhythm by themselves. But it would be a mistake to assume that qin music is devoid of rhythm and melody. By the 20th century, there had been attempts to try to replace the "jianzi pu" notation, but so far, it has been unsuccessful; since the 20th century, qin music is generally printed with
staff notation above the qin tablature. Because qin tablature is so useful, logical, easy, and the fastest way (once the performer knows how to read the notation) of learning a piece, it is invaluable to the qin player and cannot totally be replaced (just as staff notation cannot be replaced for Western instruments, because they developed a notation system that suited the instruments well). There is a saying that goes "a short piece requires three months [of dapu to complete], and a long piece requires three years". In actual practice, it needn't be that long to dapu a piece, but suggests that the player will have not only memorised the piece off by heart, but also have their fingering, rhythm and timing corrected. And afterwards, the emotion must be put into the piece. Therefore, it could be said that it really does require three months or years to finish dapu of a piece in order for them to play it to a very high standard.
Rhythm in qin music It has already been discussed that qin music has a rhythm and that it is only vaguely indicated in the tablature. Though there is an amount of guesswork involved, the tablature has clues to indicate rhythm, such as repeating motifs, an indication of phrases or how the notation is arranged. Throughout the history of the qinpu, we see many attempts to indicate this rhythm more explicitly, involving devices like dots to make beats. Probably, one of the major projects to regulate the rhythm to a large scale was the compilers of the
Qinxue Congshu tablature collection of the 1910s to 1930s. The construction of the written tablature was divided into two columns. The first was further divided into about three lines of a grid, each line indicating a varied combination of lyrics, gongche tablature, se tablature, pitch, and/or beats depending on the score used. The second column was devoted to qin tablature. Western composers have noticed that the rhythm in a piece of qin music can change; once they seem to have got a beat, the beats change. This is due to the fact that qin players may use some free rhythm in their playing. Whatever beat they use will depend on the emotion or the feeling of the player, and how they interpret the piece. However, some melodies have sections of fixed rhythm which are played the same way generally. The main theme of
Meihua Sannong, for example, uses this. Some sections of certain melodies require the player to play faster with force to express the emotion of the piece. Examples include the middle sections of
Guangling San and
Xiaoxiang Shuiyun. Other pieces, such as
Jiu Kuang has a fixed rhythm throughout the entire piece. ==Organology==
