I recently wrote three pieces on the New Testament Canticles over at the blog my brother and I share. These are the Benedictus (song of Zacharias at the birth of John the Baptist), Magnificat (song of Mary), and Nunc Dimittis (song of Simeon upon encountering the Christ Child) — all known by their first word or two in Latin. All sung/recited during the daily office. All in the Gospel of Luke.
The reflections are devotional exercises considering the content of the canticles and their historical context. I hope they are a blessing to you:
