弦 is the common word for strings of Western musical instruments (guitar, violin) or a bowstring. 緒 is more traditional and limited to Japanese instruments or specific contexts.
The kanji 緒 originally meant 'thread' or 'beginning'. The reading お is a native Japanese word for cord or string, and the kanji was applied for its meaning. The exact derivation of お is uncertain.
