As a first step, we recorded Yoel playing the basic chords of every track.
At the second stage, we recorded simple singing over the chords. I shot this brief video from the technician room that is separated by a double glass from the wood-lined studio. Daphna is singing the song “Shaamea Vatismach Zion.” Yoel is pointing to the right place on the notes using a Yad. You can also see Father Zechariah's image, in which he seems to be conducting and singing with her, reflected in the glass.
