There are 7 strings in of Guqin. The first 5 in pentatonic scale representing 5 elements Metal, wood, water, fire and the earth. The 6 string was added by King Wen when his son was died. So the 6 string is sorrowful. The 7 string was added by King Wu when he encourage his soldiers go to the war. So the 7 string is very strong.
古琴最初只有五根弦，内合五行，金、木、水、火、土；外合五音，宫、商、角、徵、羽。后来文王囚于羑里，思念其子伯邑考，加弦一根，是为文弦；武王伐纣，加弦一根，是为武弦。合称文武七弦琴。
