U.S.-Israeli musicologist David Louis plays a lyre as part of a demonstration of biblical instruments at the Temple Institute in Jerusalem January 25, 2016. Louis is among experts trying to reconstruct the notes to which prayers were chanted at the ancient Jewish temples in the holy city, a liturgical art that skeptics believe is irretrievably lost.
