There are many different kinds of poem, and so there are many answers. Verse written in iambic pentameter (the standard meter of Shakespeare and others) has 5 beats per line, as a rule. Strong stress meter has 4 beats per line with a caesura in the middle. There are many kinds of poem where the number of beats is not important. Standard or classic meters are based on the great Greek classics, and many will argue that we have put too much emphasis on forcing Greek concepts of meter onto English prosody. However, the very finest English verse incorporates a prosody that is not slavishly obedient to the Greek forms, or to rhyme for that matter. There are many ways to study and to hear the prosodic patterns in written and spoken English that stimulate and refresh the ear, and when skilfully incorporated into verse provide subtle and powerful interactions between tension and relief.
