common metre

common metre, a metre used in English ballads that is equivalent to ballad metre, though ballad metre is often less regular and more conversational than common metre. Whereas ballad metre usually has a variable number of unaccented syllables, common metre consists of regular iambic lines with an equal number of stressed and unstressed syllables. The song “Amazing Grace” by John Newton is an example of common metre, as can be seen in the following verse:

Amazing grace! how sweet the sound.
That saved a wretch like me!
I once was lost, but now am found,
Was blind, but now I see.
