This is a full transcription of the vocal, dulcimer, and guitar parts on this immortal singer-songwriter classic. (As a bonus for the piano accompanist, I have added my own piano arrangement of the intro and outro sections.)

“I remember playing it for Kris Kristofferson, and he was kind of choked by it and said, "Oh, Joni, save something of yourself!". I think he felt that I revealed too much or something, [that] I would leave myself too vulnerable.”
– Joni Mitchell (2003)
