This is a list of literature for the guqin. Qin literature should be distinguished from qinpu which contains music tablature of some sort.
There are a number of ancient sources that discuss qin folklore, qin theory and general qin literature. Some of these books are available inserted into certain qinpu (qin tablature collections). The basic contents of qin literature is mainly essays discussing and describing the nature of qin music, the theory behind the notes and tones, the method of correct play, the history of qin music, lists of mentions in literature, etc. The detail can be very concise to extremely detailed and thorough. Some are mostly philosophical or artistic musings, others are scientific and technical.
The biggest collection of qin literature in existence is the Ming dynasty Qinshu Daquan 【琴書大全】 (1590), with a collection of 22 volumes.
A very good teaching manual for the qin. Step by step with every piece explained in detail. Recommended.
