Desdemona's song from Othello, also known as The Willow Song, intended for my proposed book of songs from Shakespeare's plays for use in performances, which I'm creating in hopes there will be a demand for them, since Shakespeare remains popular. If anyone reading this knows of any theatrical company, at any level from school drama classes to professional companies or anything in between, who may be interested in such songs, please let me know.
This is taken pretty much directly from the melody as it appears in several old books. It's no doubt very old.
