Beginning of BWV 736, with an anacrusis shown in red. Play

In poetry and music, and by analogy in other fields, an anacrusis (plural anacruses) is a brief introduction.

Poetry

edit

In poetry, a set of extrametrical syllables at the beginning of a verse is said to stand in anacrusis (Ancient Greek: ἀνάκρουσις "pushing up"). The technique is seen Old English poetry;[1] in lines of iambic pentameter, the technique applies a variation on the typical pentameter line causing it to appear at first glance as trochaic.

Music

edit

In music, an anacrusis (also known as a pickup) is a note or sequence of notes which precedes the first downbeat in a bar.[2]

Western standards for musical notation often include the recommendation that when a piece of music begins with an anacrusis, the notation should omit a corresponding number of beats from the final bar in order to keep the length of the entire piece at a whole number of bars.

If anacrusis is present, the first bar after the anacrusis is assigned bar number 1.

Examples

edit
  • In the song "Happy Birthday to You", the anacrusis forms the Happy and the accent is on the first syllable of Birthday.
 
x / x x / x x / x x /  
Oh, say, can you see, by the dawn's ear- ly light . . .

Other fields

edit

In academic publishing, the term is sometimes used in an article to mark an introductory idea standing between the abstract and the introduction proper.[3]
