Variations on The Willow Song for alto and tenor recorders and guitar

Description

The Willow song is a traditional tune (first documented in a lute book dated 1583)
which was used for Desdemona’s lament “The poor soul sat sighing by a sycamore tree”
in Shakespeare’s tragedy Othello.
I have given the tune and a variation on the tune to the alto recorder
while the tenor recorder provides countermelodies.
