The lyric is generally a short poem which deals overwhelmingly with emotion, most often love, and the personal feelings of the poet. It is therefore a subjective form of poetry, unlike other major forms such as the narrative or dramatic. Often the lyric follows a regular metrical and rhythmical pattern.
Originally the lyric was a form of poetry in Ancient Greece, designed specifically to be accompanied by the lyre (from which the word 'lyric' is derived). In succeeding ages, as the lyric spread all over Europe it no longer required musical accompaniment but the form retained musically expressive qualities. It popularity in English has fluctuated over the centuries, flourishing in the Rennaissance period but declining in the eighteenth century and then seeing a marked revival once more in the Romantic era, where subjectivity and intensity of feeling in poetry was valued above all else. This has continued in modified form up until the present day.
Although its exact from may change from age to age and from poet to poet, as a vehicle for expressing subjective feelings the lyric remains a popular poetic form.
