Transcription source
This transcription is different from the what is actually printed in Ravenscroft. It is the transcription from the source cited "Songs from Shakespeare's plays, and popular songs of Shakespeare's time" from 1964. That version has the melody written in a harmonic minor mode whereas Ravenscroft's version is dorian.
Please see the link below for a transcription from his book

I am new here but maybe I could get some guidance on how to update the entry?
