This is the universal Kyivan Irmos melody of Tone 1 which applies to all irmosy.
Here it is applied to the Irmos of the ninth ode of the Canon at Matins for the Conception of Saint Anna, when she conceived the Most Holy Theotokos, Dec. 9/22, also called the Immaculate Conception by our brethren in the West.
lyrics
O my soul, magnify the most glorious conception of the Mother of God.
Let us the faithful magnify the Mother of God, wellspring ever-flowing and life-receiving, the light-bearing lamp of grace, the living temple and tabernacle all pure, even more spacious than heaven and earth.
