You have to select only good poems. For example Robert Frost Whose woods these are I think I know. His house is in the village though; He will not see me stopping here To watch his woods fill up with snow. My little horse must think it queer To stop without a farmhouse near Between the woods and frozen lake The darkest evening of the year. He gives his harness bells a shake To ask if there is some mistake. The only other sound's the sweep Of the easy wind and downy flake. The woods are lovely, dark, and deep, But I have promises to keep, And miles to go before I sleep, And miles to go before I sleep.

A good tip is when you say the word out loud clap your hands with the "beat"... you normally clap in between vowels. For example: Little red riding hood ate her dinner = 10 syllables Lit-tle red rid-ing hood ate her din-ner.... I hope this makes sense... it is hard to explain without actually showing it

I think it's not easy even for native speakers...

Is like countind the syllables of each line
