Below is an audio file of the easiest way, in my opinion, to chant the canticle.
As you can see in the pagescan from the 1940 Episcopal Hymnal below, I’m chanting setting #639 by W.H. Monk.
Here’s the “Chantable” Text of the Benedictus:
Blessed be the Lord God of | Israel;
for he hath visited and re|deemed • his people;
And hath raised up a mighty sal|vation for us,
in the house of his | servant David;
As he spake by the mouth of his | holy Prophets,
which have | been • since the | world began;
That we should be saved | from our enemies,
and from the hand of | all that hate us.
To perform the mercy promised to our | forefathers,
and to remember his | holy covenant;
To perform the oath which he sware to our forefather | Abraham,
that | he would give us;
That we being delivered out of the | hand of our enemies
might | serve him • without fear;
In holiness and righteous|ness before him,
all the | days of our life.
And thou, Child, shalt be called the Prophet | of the Highest:
for thou shalt go before the face of the | Lord • to pre|pare his ways;
To give knowledge of salvation | unto • his people
for the re|mission of their sins,
Through the tender mercy | of our God;
whereby the day-spring from on | high hath | visit•ed us;
To give light to them that sit in darkness,
and in the | shadow • of death,
and to guide our feet | into • the way of peace.
Glory be to the Father, and | to the Son,
and | to the Holy Ghost;
As it was in the beginning, is now, and | ever shall be,
world without | end. Amen.
Please feel free to let me know if you have any questions about chanting the Benedictus! I’m no expert, but I’m happy to help!
