This blew my mind a little bit and I wanted to share it with you guys. I wasn't sure which forum would be more appropriate—I almost went with Tab, Tips, Theory and Technique, but I didn't want to mess with anyone's vibrato technique! Tibetan musical notation from the 19th Century: This notation system is known as yang-yig. In Tibetan, yang refers to tone, melody, rhythm, while yig means words and lyrics. Yang-yig was apparently developed as a means to record slowly disappearing forms of vocal music, and eventually became a comprehensive scoring system.
