The guqin began with five strings and only later gained seven
The ancient qin had five strings, matching the pentatonic scale gong, shang, jue, zhi, yu; legend says King Wen of Zhou added one string and King Wu another, making seven. The ten-string qin from the tomb of Marquis Yi of Zeng and early five-string examples show the early form was not yet standardized.
Once the seven strings settled, the qin's range crossed four octaves, with thirteen "hui" studs marking the harmonics. Its notation, "reduced-character tablature," records not pitches and rhythm but fingerings and string positions — the same score can yield completely different rhythms in different players' hands.
