Come together; reconcile.
In a musical score, A Due (ah-DOO-way) is a directive for two instruments, or two sections of instruments, to return to playing in unison after a divisi or solo passage. It can also simply indicate a duet.
A Due is a Directive card. It directs the querent to come back together with another after a separation, or to reconcile elements, processes, or people that have been estranged; or, it indicates a time when such a reunion is at hand.
