Dactylic tetrameter is a metre in poetry. It refers to a line consisting of four dactylic feet. "Tetrameter" simply means four poetic feet. Each foot has a stressed syllable followed by two unstressed syllables, the opposite of an anapest, sometimes called antidactylus to reflect this fact.

Example A dactylic foot is one stressed syllable followed by two unstressed ones:

DUM da da

A dactylic tetrameter would therefore be:

DUM da da DUM da da DUM da da DUM da da

Scanning this using an "x" to represent an unstressed syllable and a "/" to represent a stressed syllable would make a dactylic tetrameter like the following:

/ x x / x x / x x / x x

The following lines from The Beatles' "Lucy in the Sky with Diamonds" demonstrate this, the scansion being:

/ x x / x x / x x / x x Pic- ture your- self in a boat on a riv- er with / x x / x x / x x / x x tan- ger- ine tree- ees and marm- a- lade skii- ii- es

Another example, from Browning:

/ x x / x x / x x / x Just for a hand- ful of sil- ver he left us! Another example from Leonard Cohen of his song "Famous Blue Raincoat":

/ x x / x x / x x / x What can I tell you my bro- ther my kee- per / x x / x x / What can I poss- ib- ly say
