In poetry, metre (meter in American spelling) is the basic rhythmic structure of a verse or lines in verse.Many traditional verse forms prescribe a specific verse metre, or a certain set of metres alternating in a particular order.n many Western classical poetic traditions, the metre of a verse can be described as a sequence of feet, each foot being a specific sequence of syllable types — such as relatively unstressed/stressed (the norm for English poetry) or long/short (as in most classical Latin and Greek poetry).
