This will follow the same format as the previous post. Be sure to read Chant Basics with the Pater Noster and Getting to know the Psalm Tones: Weeks I and III before going through this post. See if you can figure out the melody before listening to the audio for each.
Weeks II and IV:
Psalm 1
sol / la … do / ti / la
Psalm 2
fa / mi / re / do … do / re
*I think this is the first post with the “fa” clef, telling us where fa is rather than do (which lands on a space rather than a line in this scale).
New Testament Canticle
do / re / do … do // la / te / do
Canticle of Mary
re / mi / fa / re … do // mi / re
