Anacrusis is a partial bar preceding the strong beat (downbeat) of the first complete bar. It is also called a pickup bar or an upbeat. Anacrusis can contain multiple rhythmic events and does not require them to fulfill the bar.

Anacrusis example
Anacrusis (upbeat) in the beginning of Bach's BWV 736
