 The procession moves up the church toward the altar, the deacon in a white Dalmatic carrying the triple candle.Three times the procession stops, the deacon lights one of the candles from the taper and sings, ""Lumen Christi"", on one note (fa, in the Solfege system), dropping a minor third (to re) on the last syllable.The choir answers, ""Deo gratias"," to the same tone.
