Common English rhythm, called Running Rhythm(2) above, is mea­sured by feet of either two or three syllables and (putting aside the imperfect feet at the beginning and end of lines and also some unusual measures, in which feet seem to be paired together and double or composite feet to arise) never more or less.

Every foot has one principal stress or accent, and this or the syllable it falls on may be called the Stress of the foot and the other part, the one or two unaccented syllables, the Slack. (3) Feet (and the rhythms made out of them) in which the stress comes first are called Falling Feet and Falling Rhythms, feet and rhythm in which the slack comes first are called Rising Feet and Rhythms, and if the stress is between two slacks there will be Rocking Feet and Rhythms.

These distinctions are real and true to nature; but for purposes of scanning it is a great convenience to follow the example of music and take the stress always first, as the accent or the chief accent always comes first in a musical bar.

If this is done there will be in common English verse only two possible feet-the so-called accentual Trochee and Dactyl, and correspondingly only two possible uniform rhythms, the so-called Trochaic and Dactylic. But they may be mixed and then what the Greeks called a Logaoedic Rhythm arises. These are the facts and according to these the scanning of ordinary regularly-written English verse is very simple indeed and to bring in other principles is here unnecessary.
