The grammatical analysis is great. But learning to chant these suttas has also got me interested in the metre. This, of course, one eventually absorbs by repetition, but it is interesting to understand how it works.
Ānandajoti Bhikkhu has a book: An Outline of the Metres in the Pāḷi Canon
https://www.ancient-buddhist-texts.net/Textual-Studies/Outline/index.htm
There he has a detailed analysis of the Mangalasutta with light (v) and heavy (-) syllables indicated [I’ve subsituted a “v” here, to replace the special character used in the book]:
Here is a verse from Mangalasutta of Khuddakapāṭha (5: 1) together
with its analysis:
1 2 3 4 5 6 7 8 || 1 2 3 4 5 6 7 8
v − − − ¦ v − − − ¦ ¦ − v − v ¦ v − v −
a & b Bahū devā manussā ca, ~ mangalāni acintayuṁ,
1 2 3 4 5 6 7 8 || 1 2 3 4 5 6 7 8
− − v − ¦ − − − − ¦ ¦ − v − v ¦ v − v −
c & d Ākankhamānā sotthānaṁ, ~ brūhi mangalam-uttamaṁ.
